In terms of character designs, I notice I tend to do a few things. For one, I notice that I seem to like high-contrast color combinations, or I'll use color schemes that are ironic in some sort of way. For example, Iudicium/Samara Amarante, who is basically a deity representing Judgment. For hair and skin, I have her as a Black and White Beauty
. For her clothes, I also follow a black and white motif. The irony in it is that such a scheme would suggest Black and White Morality
, but in reality she operates with Grey and Grey Morality
- As the being that passes the final judgment when someone dies, she realizes everything is relative, that there's never a clear-cut good or evil.
I'm also very fond of the color combination of green and black.
As for non-symbolic color schemes, I just typically use whatever is realistic/appropriate or simply what looks right with the character. I won't use colors that don't look right with their skin/hair/eye color, and I try not to clash colors. The exception is, of course, if it's in-character for the character to dress that way.
I rarely go into the realm of improbable hair colors... Unless, of course, a character dyes it that color (For example, a quirk of a particular character of mine is dyeing his hair odd colors). The only exception to this is white hair, and is not used with human characters... Unless, of course, they dye it. In the same vein, I try to avoid abnormal eye colors, unless it's a non-human species or the person is wearing colored contacts.
Drifting away from characters and following motifs, it depends. On Earth or in other "natural" settings
, the colors are realistic for that world, taking into account things like their atmosphere, lifeforms, evolution, etc.
. But with settings that are essentially outside
our known universe, non-physical realms that technically don't even exist
in a tangible form, it tends to reflect the psyche of whomever is seeing it. That is, appearance would depend on the narrator, and the colors and visuals would be symbolic of their inner workings.
