Looking at wikipedia can give good ideas, like now, I'm looking at Hand-colorization and there are things you could use:

"Typically, watercolours, oils, crayons or pastels, and other paints or dyes are applied to the image surface using brushes, fingers, cotton swabs or airbrushes." ...

So some ideas:
 * Crayon (クレヨン)
 * Pastel (パステル)

There are normal names like color names, etc. to use as well, but these would be my thoughts
