So I have a drawing that I want to color in using photoshop or illustrator I just dont know which one would be better, I know photoshop is a bitmap related program but wouldnt illustrator be the same since all im going to be using is the paint tool? maybe some gradients. I know if i was creating it from scratch i would want to use the vector base so I would want to stick with illustrator but again wont be using any curves or lines or anything.

If i am wrong about this information please let me know as i dont want to be uninformed on the programs i plan on using a lot.
