Why not correct them then? That is what Wikepedia is all about!
I've given it a go, but the majority of popular references to "metamerism"
are wrong, so it's easy for someone to revert it back again,
thinking that they understand it.
By the way, "Color constancy" has little to do with metamerism.
It is "the everyday perception that the color of objects remain unchanged
across significant changes in illumination color and luminance level."
(that's from Mark Fairchild's book).
Most of the popular usage of "metameric" should in fact be
"metameric failure, possibly due to a metameric match having
a high degree of metamerism".
