Wolves "look" gray, but their fur is actually made of hairs where each individual hair is one of several colors (black, white and red, IIRC) depending on if you look at the tip, middle, or root.
I'm recalling that I once came across a word that describes this, but can't find it again. Does anyone know the word? (IIRC there is a Wikipedia article on it.)
I believe it is not any of:
- gray/grey (duh)
...but it's possible I'm wrong. In any case, a source that matches the above description is appreciated. Googling has been... unhelpful; I either haven't hit on the right combination of terms, or am being buried in unrelated results.
