Egg crate cover -- Can I paint it?

I'm thinking of ditching my glass tank cover to help with my temperature problems (and get that beneficial gas exchange all the kids are talking about).
But I'm wondering if i could paint the white light diffuser black to make it more aesthetically pleasing.
Has anyone ever done this? What type of paint would you recommend?

 

Why use a cover at all? Do you plan on stocking a carpet surfer?

 

Baby-steps to an open-top system. I switched over to the egg crate and it turns out that I really don't notice the white at all. Still having temp issues. I'm thinking about getting some mounting legs for the lights to raise them up a few inches. Will this help?

 

I just bought black egg-crate from RONA.

They have four colours:

white, black, silver, gold.

I suspect the silver and gold have been painted. The black and white apparently are not.

 

What's a RONA? Is that some sort of home improvement store? Thanks for the tip!

 

if you want to paint it try krylon fusion paint for plastic and glass. it is tank safe once it is dry

 

A "RONA" would be the equivalent to a "Home Depot".
