I’ve been seeing some art of Reyes that just pales in comparison to the guy himself, so I made a palette for Reyes’ skin tone to get you started.
Writing with Colorhas a great post to help with describing skin tones, and while it might be aimed more towards writers, there are some really good visual aids - it’s also an excellent resource for artists wanting to draw a fictional character they have a written description of but nothing visual to go on. There’s honestly a ton of good stuff here, and I’d really encourage you to follow this blog, even if you’re not a writer!
I get that selecting the right tones can sometimes be tricky and sometimes different lighting can make things even trickier - but if you look at the swatches above, you’ll notice that even the lighter tones are a kind of tawny orange-brown. It’s really important that we look critically, both at our own work and the works of other artists, and try to get it right.
