Well, no, not filter or transmit of the object color. I meant the intensity, 
or saturation, of the resulting colors. The more I think of it I understand 
your confusion with my question. Adding either white or black to the overall 
color intensities to get lighter or darker dispersion is what I'm talking 
about. Not reducing or increasing color contrast.
That obviously isn't simply "refracted" light, as it were; more so a color 
addition/subtraction effect. And it still doesn't quite sound right, since a 
filter value would indeed need to go along as well.
Think in terms of the 'irid' keyword and it's thin or thick "film" which tends 
to be either subdued or very colorful depending upon the amount given, if I 
have that figured right.
Well, besides this, I say again it's great to see in this possible in 3.1.
