Metamerism is NOT simply looking different under different lighting or a 
predictable color cast brought on by differing source lighting.. That's 
a given optical phenomenon...

Metamerism is the tendency of different colorants to respond differently 
under different lighting conditions, leading to optical color crossovers 
and inconsistent color casts under differential lighting..

Let's get what we are talking about clear first, before we posit 
solutions...
