Color changes? Maybe too much light?

So I have two pieces of coral that over the past couple weeks started changing colors. A regular austrailian orange lobo colony and beautiful acan colony I saved from an LFS. The acan colony was black with orange stripes and neon pink mouths. The black has turned to a maroonish color. The lobo has gone to this maroonish color as well. Are they in the process of browning out? Water params seem normal with no app changes. All other pieces in my tank are fine and colored nicely. I'm just looking for some opinions here. Thanks

Got some pics. These are without actinics and under 250watt 20k's.

Here's the black acan I saved.

Here's the lobo

When you changed lights did you turn down the time of the new lights

I haven't changed lights in about 2-3 months. Both pieces came in after I got new bulbs. Both pieces, did however, come from the same LFS that likes to run his corals under straight actinics. The pieces were nicely colored until the last two weeks or so.
