Photoshop.
if you don't have it or want to don't want to use it I would say markers or colored pencils.

Water soluble crayons are really cool. They're really bright and give your drawing a "pop art" look.

If you already did the drawing in black, there's pretty much no way you're going to be able to add color to it and make it look realistic... it's going to look cartoony.

watercolours are bright and fun to use, although the paper makes some waves where the water is absorbed. After it's dry, you can use a thick book to press it to the original flat shape, but it will take a while till it's completely flat as it was before.

i'd say it's worth it if you like the watercolour effect.

If it's in pen watercolours might cause it to run, try it out on another sheet of paper first.
Copic markers work wonders.

I use Copic markers for coloring my line art. Depending on what type of pen you used to ink it, I'd be careful of using any waterbased media to color. Unless of course you are sure that you used a pen that will not bleed/run/smear (I use Copic Multiliners, as they are specifically marketed for use with Copic markers, but they also produce runproof and bleedproof lineart for any moist media.)

If you are not sure of the pen type, try making a mark on a separate paper and letting it dry completely. Then get it a bit wet with some water and try to smear it with your finger. You'll know pretty quick whether or not you should use moist media on it.

For dry media, I prefer prismacolor colored pencils, as they go on very smooth, and are soft so that I can attain a less sketchy look with my work... they are also bright and colorful and easy to blend together.
