Tans a mediocre colour in reality, but that's why i like it as a sheezyart theme, as it will not be so bright it will burn your eyes, and it makes everything easy to read and make sense of.
I think this is a better solution to tan as it feels neutral too..
Now! I am off to learn to shade as I'm going to draw something using this colour scheme. (Seeing as you know how to do this really well, any tips asides from practice? I need to leaaaaaaaaaaaaaaaaaaaaaaaaaarn)
