How is this an F color??

[lovedogs]

Just a fun Friday afternoon thread

I love window shopping for diamonds even when I have zero intentions of buying them, and came across this little guy.










Is there something I'm missing about the effects of fluor on an F that makes this look pinkish/blue to me? I expected it to be strong blue, but it's only medium so extra surprising to me. Or is it the lighting?

Either way it's really neat!

Cert below:

Almost all videos and photography is done with LED lighting these days.
There can never be any fluoro showing because white LEDs dont have any UV (they cut out at 415nm)

Never judge diamond color by pics or videos.

Judge it from the color grade assigned by a reputable lab.

light contamination and white balance setting issues.
or what Kenny said.

Are those from JA? Because I have found their photos will show the same color grade diamonds looking different over different photos.
