What is the meaning behind different robe colors?

Why do Buddhist monks wear orange?

Note: Buddhists also wear red or yellow, depending on different regions, like Tibetan Buddhists wear red, Chinese Buddhists wear yellow(not sure) etc.

Answer: Because Hindu ascetics(Yogis/Sannyasis) used to wear orange. Buddhism came out of Hinduism/Vedantic traditions(which are atleast half a millennium older than Buddhism) and thus its impact on Buddhism is clearly visible. There is much more common between these two spiritual traditions(Buddha himself was from this religion and never spoke ill of it, nor tried to bring radical changes in it. Much of Buddhist philosophy already existed before Buddha as Sankhya and Yoga schools of Hinduism. One of the Gurus of Buddha(Alāra Kalāma) was from Sankhya school of Hinduism. Sankhya & Yoga are atleast 95% similar to Buddhism, thus many things are common.)

So, now, why did Hindu monks start the practice of wearing orange robes?

Short answer:- Because orange/saffron (or red or yellow) is the color of fire, which is pure.Long answer:-This Indian tradition dates back to Vedic period. Vedas are oldest Hindu scriptures. Early parts of Vedas deal with rituals, society & ethics, while later parts, called Vedanta(core texts of Hinduism) deals with philosophy, spirituality, monastic life, yoga & meditation. Vedantic texts mention symbolism behind wearing of orange robes(which is related to early Hindu rituals). Buddhism just accepted/adopted/continued this tradition.It was Indian tradition at that time, which had origins in Hindu Vedas. So every Hindu Sannyasi/Yogi wears orange/saffron robes. The oldest Hindu rituals were offerings(sacrifices of grains, milk, butter etc.) into fire. Therefore, fire symbolised sacrifice. Since color of fire is orange(or red or yellow), the color also represented sacrifice(of our sensuary/material pleasures). Even today, saffron/orange, and also red and yellow are considered sacred in India by Hindus and used by Indian Yogis.This Vedic/Vedantic(Hindu) idea of monasticism is based on symbolic interpretations of early Vedic fire rituals(called Yajnas), the body of a Yogi monk symbolises altar of yajna, his conciousness is the fire into which he/she sacrifices(burns) his material desires, animal instincts and ‘sad-ripu’(six enemies- attachment to word, lust, anger, ego, greed & jealousy), his Prana (life force/Qi) is the sacrificer & the act is done by meditation. This metaphor for Yoga is discussed in the oldest & most important Vedantic/Hindu texts like Brihadaranyaka Upanishad section 2.2, Chandogya Upanishad, Kaushitaki Upanishad sections 1.4 and 2.1–2.5, Prasna Upanishad chapter 2 and many other later texts. In fact, there is a whole Upanishad which deals specifically with this topic only, i.e. , Pranagnihotra Upanishad. Therefore, the spiritual significance of orange robes is that it reminds the monk that he has to sacrifice his sensory/material pleasures, and that his body is like the sacred sacrificial fire of Agnihotra/Yajna for this purpose, and thus a monk is as pure as fire, which purifies everything and gives light/knowledge to everyone.

Conclusion: Buddhists wear saffron/orange robes because it was an older Hindu tradition which they appreciated/adopted. Thus, the symbolism(orange=ritual sacrificial fire) behind this is absent in Buddhist texts(correct me if I'm wrong), but is discussed in detail in Hindu texts. Most Buddhists don't even realise this meaning because most Buddists are outside India and they don't study Buddhism with proper Indian cotexts and are unaware that Buddhism was and is, more or less, a part of Hinduism.

The Theravada Bhikkhunis in California and the rest of the United States wear medium brown robes with ever so subtle hint of yellow/orange. A Bhikkhuni is a female monastic in the Theravada tradition and there numbers are growing.The first year a lay person can try out the robes and wears white and is called an Anagarika.

The meaning of use of different colors is expression of own identification, no-unity, pride. That being the readon, like here, the Buddha allowed certain colors and forbid others. Yet desire for identification is like Dhamma timesless, and so the show goes on. There is a simile of a donkey wishing to be part of a heard of cows, thinking he's one of them: "Even their robes are different...", but of course such isn't, if one is badly informed, or bond to own-taken tradition, not the last measure. What ever lies in the spectrum of saffron, dirty yellow, brown, not shiny orange... might be fine. Shiny is improper, as a monk would need to "destroy color", red is improper, dark is improper, green, blue... not to speak of white and gray, are improper, as well as rose.

[Note that this isn't given for stacks, exchange, other world-binding trade and use, but for an escape from this bond]

The Buddhist Vinaya code calls for monks robe to be if "discarded colour" or "spoilt colour" i.e. colours not of distinct recognition such as red, blue etc. During Buddha's time, robes are initially made from unwanted clothes collected and sewn and dyed wth tree barks, which turned them into dirty brown, even purplish or mud orange.

As time passes, the robes offered in different regions are commercially made using the available dye/tree bark in that region. And while it helps to identify where the monks hail from such as Sri Lanka, Thai, Myanmar etc. Hence, you find each with a tinge of tonal difference. No big deal about the colour difference.

However for the Mahayanese Sanghas as those from China, Taiwan, Japan & Korea, Vietnam etc. you'll need some historical knowledge on how Buddhism travelled and when. In ancient China before Song dynasty, monks wore dirty coloured robes, purplish orange, using a colour mixed from leftover dyes. However during the Song Dynasty, the emperor took refuge in the triple gems and appointed his master as National Master (or Advisor). Historically yellow was recognised in China as royal colour, that only royal members are allowed to use. Since Sangha members are being recognised as the teachers of the Emperors and royals, they are therefore accorded the right to adorn in yellow robes. And the emperor insisted that his master and all sangha be accorded the royal rights with him offering the yellow robes to all monks in his country, and decree that all ministers and countrymen/women pay due respects to monks as they do to the royalties. While training in temples, samaneras wore white, after pabajja ordination, the trainees or novices are allowed to wear the grey coloured 罗汉服luohan fu (arahant clothing) as their daily wear (1 of the 3 robes) as they worked towards their spiritual development. As temples then were usually built high up in the mountains where water are shortage, washing becomes restrictive. grey being the discarded color and not so easily dirtied as white, it became the basic anenities of a practising hermit/monks esp. in Chan/Zen that was prevalent. Only when one had completed the higher ordination of upasampada, can one then be accorded the yellow robes befitting a master. It has to be noted that in ancient China, temples (寺) are recognised as equivalent to Minstry of Education and the abbot of temples accorded a rank same as a full Minister, approved only by the Emperor himself. So for monks in yellow robes, representing royal patronage, even Ministers or Generals had to pay their respect first and not other way round as if in audience with the Emperor himself. Korean & Japanese scholars had started learning from China during the great Tang Dynasty, the traditional Japanese culture are mostly adapted from the Tang Dynasty, including its kimono, kanji, busdhism etc. While Korea adopted mostly from Song & Ming Dynasty of China. However, in terms of Buddhist practises, both Japan & Korean follows exactly the same tradition as practised in their lineage in China , eg. Tiantai (Tendai), Chan (Zen), or Pureland perhaps with very limited alerations thru times.

Since I'm visiting a Buddhist temple here in Chiang Mai I thought that I would answer. Brown robes can eat only once per day, orange/saffron robes eat twice a day and the maroon (Myanmar) robes can eat whenever they want. That's the word among the monks (they take eating very seriously).

of all the responses here, i am only surprised that Theravadan women wear white. my experience is in Nyo Ho E (authentic Dharma clothing) as provided for in Japan especially through the teaching lines of Kodo Sawaki-roshi at Antaiji and brought to North America by trainees through there including Yoshida-roshi and Joshin-sama to Tomoe Katagiri-sama and Blanche Hartman-roshi. white seems unusual because it is a basic, or primary color (as would be blue, yellow, red, and black). but there are black robes for training priests in Japan (though the color is supposed to be "off" somehow). by the same reasoning, i guess i should be surprised that yellow is mentioned a lot, but i am very used to seeing it. it may be that the "yellow" is "off" somehow. i think it should basically be modest, and what looks modest has a cultural factor too. black is modest in Japan. i think grey is worker / modest in Korea. maybe in the US, it should be clothes from Walmart ... i don't think that's gonna happen but, that's my sense of the feeling. very ordinary.

" Bright yellow - China

Black, brown, gray - Japan & Korea "

I want to add this trivia. The original colour of monastic robe in China was black or gray much like its brethen in Japan and Korea from the Dharmaguptaka lineage.

https://en.wikipedia.org/wiki/Dharmaguptaka

However Master Hsing Yun the famous Chinese monk from Fo Guang Shan in Taiwan found that the gambling obsessed Hong Kongers associated the colour black with death and hence was considered unlucky and did not welcome him. So for public appearances he wears the 'golden' yellow robe along with a bright red kasaya, as a form of skillful means. Taking this precedence Chinese monks begin to wear bright yellow robes.

Further more based on my association with the temple and brief experience as a short term novice monk I observed the following:

• Within the monastic compound Chinese monks wear bluish gray tunic and trousers inside for cooking, cleaning, meditation and to sleep.
• For ceremonies and public appearances a black robe called the Haiqing is generally worn, with a dark maroon Kasaya.
• During public ceremonies only the ceremony conductor wear the yellow robe and red Kasaya.
• A brown cassock maybe worn for travelling.
• You must take off the robes before you go to the bathroom, going in with only the gray inner wear

Originally, in the first years or so of the sangha, monks would make their own robes from scraps of cloth they found in the trash or in cemeteries, etc. They would color them by rubbing them with dirt or clay. After that, any earthy color, found in dying leaves of trees, such as red, yellow, brown, orange or maroon, was acceptable. Within the Theravada, there's no hard significance between the different colors and shades of colors in this spectrum. However, you will often find that all of the monks in one temple tend to have the same color and shade. This is often not 100%, because they accept their robes from dayakas (donors) and they would not reject a robe because it was a different shade. Similarly, a monk might have brought his robe with him from another temple.

I did see one temple, however, where the head monk had yellow robes, and all of the others had orange robes. But this was just their practice, and is not from instruction of the Buddha.

Oh, In vinaya (code of conduct in monastery) Buddha allowed many types of die to be used for the robe. Bark from different kinds of tree, or even red color from clay. so naturally, there would be different shades. Bark from Jack fruit tree produces brownish color where red clay (like what Andrei said above) produces reddish color.

The command was the color Kasava--that means dirty or stained brown. No other color allowed. But the patches and dyes varied, so the Buddha approved the MINOR variations of brown. The idea behind the color is that this is the color of mourning. The entire tricivara is based on ancient Hindu widow's weeds. No one ever answers THIS question correctly. Clerics today should all be wearing a uniform Brown, rather dark brown, end of story.

From my research it looks like the reason that original kasayas (stitched robes, made from leftover pieces of fabric and clothes found on trash piles, taken off corpses etc. - basically the discards of civilization) were ochre or brown-red, is because they were washed with red clay, used as a cleaning agent.

Ochre was the most available color of clay around the area Buddha lived and practiced at.

From this, we can extrapolate and assume that different colors originally derive from different types of clay available in whichever region Buddhism spread to. Later, the colors were standardized by schools and various different dyes were employed beside clay.

Tibetan lineages wear the maroon color of the cloak out during a Puja, and the yellow out if at giving a teaching.

With the historical significance of the color of the original robes explained by other posters, I'll just add a color chart to identify what regions different colors are mostly associated with today; keeping in mind there are exceptions:

Spice colored robes (shades of curry, cumin, paprika, saffron) - Southeast Asia

Bright yellow - China

Black, brown, gray - Japan & Korea

Maroon - Tibet region and diaspora

White or pink - Theravada women wherever they may be located; although it is noted fully ordained Theravada nuns are rare.

There are some differences in style as well; more detail at source:

I believe initially the robes were mostly yellow as this was a color of renunciation in the locality at the Buddha's time. As the Dhamma-Vinaya spread the different robe colors occurred due to the local dyes monastics used in their respective localities being different shades and colors.

I do know that in the Theravada tradition at least in Thailand and Sri Lanka there is a differentiation in colors between forest monks and city monks.

The robe dye is allowed to be obtained from six kinds of substances: roots and tubers, plants, bark, leaves, flowers and fruits. They should be boiled in water for a long time to get the dun dye. Saffron and ochre (from the jackfruit's heartwood) are the most prevalent colours today. Though there is a tendency amongst forest monks to wear ochre and city monks to wear saffron, but this is not always the rule.
