Its possible that it is tinting in the glass itself. Its also possible that it is just how the clams are. I know some corals will get slightly different colors from the top than the sides because that is the most intense lighting angle. Not sure if clams will do this but I suspect it is possible.
Why are colors different looking overhead vs straight on? Let’s just say I didn’t excel in science. I’m guessing it’s angle, but woul love to see the same color both ways..lighting is t5 two aqua blue special two blue plus.

Huh.....thanks, hadn’t thought of tinted glass.
The organisms have evolved micro angles in the structures containing the pigments and zooox to direct the reflected light.
Many corals do the same.
You may also notice some color change when the clam moves. Or If disturbed or after wc etc. this control is a precursor to the use of chromattaphors in octopus and cuttlefish.
Basically they can change color slightly to increase and decrease photo synthesis. Very handy for critters in shallow water under tropical sun.

In the arena.
the difference in color is not the intensity but rather how the water changes the speed and angle of light. the same physics that change the wavelengths that make a coral look different from the top versus viewing from side apply to clams - notwithstanding the affects of the glass as well.
It not just specific to clams, same thing happens with corals. Honestly that's a dang good question.
