Eggcrate colour and bottom

[Ryan]

I am planning a small frag tank and have a few questions. My first is does the colour of egg crate change the amount of light a coral will get over a period of time. I am wondering because we all know black will absorb a lot of energy from the sun and get hot right. So If I use black egg crate the black should absorb a lot of the light and with the coral plugs on black egg crate would they not receive light a lot better than if they were on white? White reflects alof more energy because its a lighter colour.

My other thought in conjunction with the coloured egg crate was painting the bottom dark as well. How much do you think this would effect the light the corals would get?

I know the black would help make the colours of the coral stand out.
