Color is a most powerful content of an object.
Though so, lighting must be adequate for
the object to radiate its color.
This is why at night, nothing seems to have color
until a ray of light flashes onto it

Modelling with computer, you dont get to dirty your hands.
All you got to do is manipulate the software capabilities.
Photoshop is one great 2D tool for the job.
