@DefyStar Black absorbs light, so you can make things stick out more by being brighter. Otherwise I might just not be understanding your vision and I should leave you to cook.
@DefyStar You could use it strategically like an outline for your foreground troops to make them pop or if you're looking for like something kind of dark and evocative, you can play with negative space with bolder colors by saturating your colors.
@DefyStar An example on this page would be in panels 3 and 5 you could add some blues in there. I've been reading Transmetropolitan and this is an example I can think of
By the way, do check out "I Am Frankelda" by Cinema Fantasma if you can. It'll be on Netflix and HBO Max has Frankelda's book of Spooks, too. Hauntingly pretty stop-motion.
