Lps colour change?

[TaioneReefer]

Hey guys,

So.. recently about 2 months ago. I bought a couple frags of hammer, and they were Bright bright neon green. really beautiful.

but I ve started to notice that their colour is starting to fade. not as green. almost turning Brown under white light, where as it used to keep glowing in green.

same thing is happening with my neon candy cane coral. its just not as bright green anymore. it used to glow in the corner. now its not as noticeable.

but the thing is, their growing like crazy. their getting really big in size. so i dont think i m doing anything wrong taking care of them..
