I'd ask whether the material it is sitting on is white in real life.
I doubt it is, but I'd ask.
If a vendor is taking FCD pics at my request I'll ask them to be sure there is something white near the diamond, and preferrable white is the only thing it is resting on.
Then I know if that known-white-area shows up on MY monitor as anything other than white, I can sort of correct for the error it in my brain.
For instance if the known-white area looks a little greenish on my monitor, I'll know the stone itself is really a little less green than it appears in that pic on my monitor.
You'd think anyone selling FCDs would not place a Yellow FCD on a yellowish surface if the pic is for a customer to judge the yellow color.
Either they are clueless, or trying to make the diamond look more yellow or concealing windowing/leakage.
If that background is white in real life, shame on them for not matching the white balance setting of the camera to the light source they are using, or messing with the color with software.
When I wrote that photographing the color of FCDs accurately was difficult I was not referring to blatant operator error things like these.
I'm not saying any of these IS what's happening, but I'd ask questions.
You are selecting based on color so they should be able to tell you what they are doing.
