Black Lace Quake sudden color change.

Huh, very strange! He's very pretty. I don't have any good advice. The last time one of my males went through a color change like that he was glowing because he was actually a pregnant female...

That was my first thought. Actually, when I read the thread title, I thought of that thing that happens when they turn totally grey, but this doesn't look like that based on the pics.
