paste diamonds with colour

[phaedrus]

hi,
still playing with my gems...
:D
I tried getting more colour out of em but Im not too happy,
any comments?

It does not look like it is refracting the light correctly. The colors look kind of cel shaded or matte like. Have you tired using gradients to smooth out the color change down the spectrum?

sounds interesting,
if youre not to busy could you briefly run through how do do that?
I'm using a combination of interference and thin film for the colours, with colour highlights..
