You ask
Does anyone know how to get a visa to be able to travel on the Colombian passport for entry back to the US?
Unfortunately, you cannot. Visas are by law to be issued only to "aliens," which you are not. From the US Foreign Affairs Manual, in particular part 9, the handbook for consular staff:
You may not issue a nonimmigrant visa to an individual who has been determined to be a U.S. citizen.

They did not care that I was a dual citizen. I prefer to travel on my Colombian passport but unless I get a visa, I cannot..
Exactly. To enter the US you need a US passport, period. Colombians require a visa, and as you're also American, you cannot get a visa.
Whether you tell people in the DR you're a dual citizen is irrelevant - without a US passport check-in staff will not let you board a flight to the US. Although you'll be let into the US, the airline could be heavily fined if letting you board.
So you'll need to get a US passport or transportation letter at a US embassy.

You'll need a US passport. If you tried to apply for a visa on your Colombian passport, you'd be asked what other citizenships you hold. Once you tell them you're a US citizen, they'll stop looking at your visa application, because visas are only for foreigners. So while you may prefer to travel on your Colombian passport, that's not an option in this case.
If you don't have a US passport with you (or don't have one at home someone can send to you), you'll need to contact the nearest US Embassy for assistance. They can handle passport applications, but it may be quicker to get an emergency travel document to get back to the US, assuming you are in a hurry to get home. Here's their page on lost/stolen travel documents (not exactly your situation, but similar), and on requesting an emergency appointment. You can also email "passport and citizenship inquiries" to [email protected] if you have questions about their local procedures.
