It depends on what you consider a colorful fish. It also depends on what other fish are going to be in the tank. Guppies are very colorful but there are only a few fish that don't attack them. Swordtails are really colorful and they do well with other fish. Tetras are also very colorful but they don't go well with long tailed fish because they become fin nippers. Platys are another option they tend to be very colorful and do well with other fish. There are also chinchilids but they don't go well with other fish. Those are about all the naturally colored fish but there are the neon glass fish that are injected with dye through a hypodermic needle. (not my favorite)
