super cool. I love a good outline too
I paint but still have trouble finding colors digitally. This website is pretty cool, you can download the palette into Aseprite and probably most programs. I also started to think of giving highlights a sun-like "yellow" tint, and having the shadows be closer to the actual color, with maybe an exaggerated deepening of that color by increasing either blue, red or green to darker hues. The yellow highlight feels like the warm sun rays hitting only some parts of the image- just some shade under a tree seems inviting because its closer to the "real" color
