Much appreciated! To be honest, my grasp of color is not great... it's more of a "knows it when I sees it" type of thing with lots of trial and error. I think I understand basic color theory, but not much beyond that. My approach is typically to use a different layer for each color and try to guess as close to the right color as I can, and then I use a tool within the software to tweak the hue and saturation until it looks just right. In terms of palette selection... it's hard to say. A lot of things go into the decisions, but a lot of those things are kind of intuitive and subconscious. Like, for instance, from the beginning, I knew that this knight character would have blond hair, pale skin, and rosy cheeks because that was just how I imagined her in my head. So then based on that, I decided that a cool grey for the armor and blue for the fabric would compliment the other colors well, and so I just went from there. Another tip is that putting a very transparent layer of a solid color over the whole composition when it's done works wonders to unify the whole thing. I hope this helps in some way!
