If you want to describe the light's color accurately, you could use the xy or u'v' coordinates on CIE colorspaces or state the CCT (correlated color temperature) and duv (deviation from the black body radiator which i call tint). I also try to present this information in my reviews. CIE president Yoshi Ono has given many good presentations about the subject and what people actually prefer, this being one of them:
