Let's use an extreme example. Even if a BLACK or DEEP BLUE round diamond was cut to ideal proportions. Put it beside a d colored diamond and I am sure you will see a massive difference.
That's an entirely different subject, IMO. On the D-Z scale, I believe that the difference in light performance would be imperceptible to the human eye. Black diamonds have a different carbon structure and absorb light instead of reflecting/refracting it.
I think I would have to disagree. Technically any visible colour means some wavelengths (and therefore some incident energy) is being absorbed - the longer the light path through the stone the more energy is absorbed, and the lower-energy the final output... texbooks aside though, I know that when comparing my well-cut J RB to a high-colour stone of similar size and proportions my J looked "dimmer" and "softer" - visibly less bright, and the higher colour also looked bigger thanks to looking brighter... That's only when the stones were loose side by side though - once set, or by itself, my J looks plenty big and bright and white to me!
Subjectively, this is my experience as well. Tinted stones produce a softer shade of "white" light. But I am not sure that can be labelled as "worse performance", do you? And perceiving color seems distinct from perceiving less "light return" in a practical sense, too.
Then again, I think scintillation and contrast patterning are so much more important for beauty that brightness, so there is my bias.
chappy diamond color in 2mm stones won't matter much.
