Faded Mushrooms

[Eric55]

I had some bright, blue mushrooms that have slowly turned to a pinky/purple color.

They are on the bottom of the tank, about 20 inches away from a 150 metal halide light and 2 fluorescent bulbs.

Should I move them closer to the light? Will they regain their color?

Thanks for any suggestions you have!
