Mood, but most people are grumpy if they don't eat.
Mine have a few colors
Moon-silver, Liquid Topaz, Amber, burning brown, and Coal black.
Moon Silver only appears if I've done something to like make my mood go really crazy. Topaz is genuinely happy, Amber is either I haven't eaten for a while or it's a common time. Burning Brown is usually when he's around people, usually vampires, and he's fine. Coal black is when I'm very thirsty or angry. Any questions?"
