In my opinion, it's a waste of time for TheChipGuide to use separate submissions of chip photos to define color variations. You can make a chip color look any way you want with a picture editor even if you aren't trying to deceive anyone. The only way to convince someone else that you have color varieties is to take a single pictue (or scan) of all the chips together and submit that. Even them, there's no telling what caused the color variations when you are looking at multiple old chips that have been exposed to different environments over the years.

A reference guide (like TCR or TCG) needs an arbiter to decide questions like this. Dividing decisions on which submittals to accept and which to return can't be done by a committee or team members making these decisions individually.
