When I started with photoshop CS6 [ Colorisation ]

Here you can see how I started on photoshop (cs6) in the first year of my studies. The goal of the exercise was to only make the color on photoshop.

First, it's advisable to start with the darkest colors, then continue with the lighter ones. And finally the reflections and shadows!

[Always create different layers for each step in order to make color motions]
