best lights for blue mushrooms

[klongo]

I purchased a rock with 13 beautiful blue mushrooms on it the other day. In my tank they look a little reddish/purple instead of the blue they were. I was looking at the tank with the lights off the other night using a flashlight and they showed up a beautiful blue. So, (on to the question) -- I'm thinking I need different lights - but what range would bring out the blue color the best.
I have T5s with 4 10k and 4 7100k actinic bulbs right now.

Im not posotive this is your problem, but if you remember kip(dunno if he's still here or not) he used to always swear by the true atinic 03's over the 7100K blue. I agree with him, Ive used both and true actinic 03 bulbs really have better quality. Id reccomend switching.

Thanks. I'll have to see if I can find true actinics in 80 watt T5s. the selection in that size isn't the greatest yet.
