The interface-elements are called:
ActionButtonXCooldown (where X stands for the specific button-number)
or MultiBarBottomLeft(etc.)ButtonXCooldown (specific for each bar)
ActionButtonOverlay1 or MultiBarBottomLeftOverlay1, etc.)
The problem is, that the "Cooldown"-Element is also shown when your abilities are on a normal cooldown. So if you need the "spiral"-thingy that shows you your cooldown (if you don't have OmniCC or else), i think it isn't possible to fix that. Otherwise i would need someone who can script a loop that sets the alphas of every button to 0.
You could also try a:
ActionButtonOverlay1:SetAlpha(0);in your script addon or just type
/run ActionButtonOverlay1:SetAlpha(0);if the Overlay1 is responsible for the "red" - i'm not sure if that's it, it pops up randomly.
Didn't test it yet, but it could work.
Nevermind... seems like it doesn't work... the cooldown-thingy can be removed, but not the color in the background
