Recently I've started to believe that values, drawing and edges are pretty much 4/5ths of the painting process with color being the icing on the cake. Color is just the thing that people tend to notice first.

One of my teachers put it in a way that I really liked.

"Color gets all of the attention, but value does all the work."

In other words color is the pretty sister that can get by on looks, and value is the smarter, less popular one that she has to cheat off of to get a passing grade.

I mean seriously, we all view slight changed in color diffrently based on how the rods/cones in our eyes work. Some artist and art students I know are even color blind. However, value is pretty much universal right? I mean looking at a drawing most people, I imagine, will come to the same conclusion in regards to which part is darkest and which part is lightest
