What gives the comb its color?

There is the same diversity for animal horns as for hair: Blondes, browns, blacks, reds, whites. Smooth and curly. Thin and thick... The color of the horn depends on its natural pigmentation. Each horn is unique, and therefore each comb.

We can have a preview of the colors of the future comb from the planing stage, but some details are only revealed at the last moment, at the time of polishing.
