Slight thing to consider though, if you REALLY wanna go hard with color metaphors. If you remove colors from something, eventually, I think you'll get white, not black, cause white is (as far as I know) the absence of all color.

White and black are both the absence of all color.

Additive, like mixing pigments, white is the absence of color. Mix enough pigment together, you'd eventually get black.
Subtractive, like mixing lights, black is the absence of colored light. Mix enough light together, you'd eventually get white.

So black is the absorption of all color, white is the reflection of all color.

god, why the fuck is color so fuckin weird
