I do not know how someone sees green in their moissanite in the sun.
Me either. Regardless of color the sparkle is BLINDING and the stone could be purple and it would be hard to see, lol.
'Warm' is subjective, that's why they do color grading. Is H described as warm on any diamond grading scale? In a case of white vs warm diamonds the H would still be in with the white. It's not a warm color. Sometimes I but more often J or K is when you start to get the 'warm' description in color grading even though *some* people are sensitive to the every so slight color in H colored stones.
DH sees fuchsia as pink because he can't see the purple/blue tones. DS says it is purple. Neither one of them are correct, it's still fuchsia!
