Do they not see it at all and interpret it as still being dark? Or are they aware there is light but just aren't as bothered by red light?

It is less bright as it is being filtered through red.  Some species seem unable to see past the clear red plastic, but other see through it with no issues at all.

 

I tried once with my colonies, but my Myrmica and Formica could see right through it.  I eventually just left it off and all of my colonies are now used to the light.  It makes moving them interesting, but it also makes observation so much better.

If I'm not mistaken, I think they see red light the same way we see infrared light... we don't. A piece of translucent red plastic would probably look the way a plastic infrared filter looks to us--black.
