bleaching palys?

[squishifishi]

are these bleaching? If so, what could be the cause and what should I do? They are shaded by a huge bunch of xenia overhead so it seems unlikely that they would be getting too much light. All my other corals are doing well, including my other palythoas of the same variety...
these are in my pico and the light in a red green and blue led that can change colors. would it be beneficial to leave it on just blue instead of all three for a few days? here is a picture, it's not the best but see how it has the patchy white around the mouth?
Thank you for any input!

I have certain z&p that thrive under the red and green spectrum and others that do not.. this just may be one that needs more blue spectrum than r&g

it's just a common red and green button polyp i think. will feeding it more often help it be healthier? are there any non-light-related causes of bleaching? thanks!

i was doing some thinking, and i realized my light is on for like 13hrs a day! that's probably way too much huh. I am reduceing my light hours now by waiting until a bit before i leave to turn it on, and shutting it off BEFORE i go to bed. i hope that helps some. any other suggestions?
