I do agree with this. I just want to add that the "thinking like an artist" doesn't have to be as intimidating as it may sound.

I don't really do any visual art outside of graphics programing, I don't see myself as an artist, I'm very much not a visual thinker, and my deuteranomaly does make some aspects of my work harder at times.

Besides all that I've found I can do a good job and get some really nice looking results just by focusing on an understanding of the underlying equations and common tricks like mentioned above.
