Fancy intense Brownish Yellow and Vivid brownish yellow

[nehalkind]

I observed that in brownish yellow diamond , either it comes fancy or directly deep or dark
but i dont know why its not showing intense brownish yellow or vivid.

are they turning to some other shades. it shows such color very rarely

From what I understand, you don't want a lot of brown to be prominent. You want the brown to be a secondary shade......to accentuate the yellow. The more brown you see, the less it is worth.
