In this little tutorial video, we go over our usual process for generating color palettes and shading sprites when working on pixel art. We use LibreSprite (which is functionally identical to Aseprite) but this should work in just about any pixel art program that lets you generate palettes like that. We are not experts and this is not THE way to do it, but this is OUR way to do it and hopefully the advice in here is helpful to someone.
