Oh I do love messing around with colors. ^u^ My personal favorites are mainly dark, like black with dark blue and then silver for accents, or natural colors that are on the darker side. I do love some good neon accents sometimes, as long as it isn't too overwhelming. As far as those neons go, a very dark blue with some mid-tone blues and cyan for the neon would have to be my favorite, that or a purple equivalent. Lately I've been pretty enthralled with working reddish purples like plum and burgundy into practically everything I've been drawing. Which isn't much, but it's there. Those dark reddish purples work really nicely with bright yellowish greens. I could keep going on for ages about this topic if I'm being honest.. ^^'
