Question on Color grading.

[lakai]

If certain parts of the diamond have noticable color, but the rest of it is lets say a F or higher, how is the color determined ??

If you mean that patch of red and orange at about 10 o' clock, that is a reflection most likely and not part of the diamond. Am I understanding what you are asking correctly?
