The metal frame of the vanilla labs becomes noticeably darker (and maybe greyscale?) when active. This doesn't seem to happen to other labs, including the otherwise very similar AAI burner lab.

I also sometimes notice active labs that are just dark greyscale with no color animation on menu background scenarios. This seems to happen to newly placed labs, which start animating again when a new research begins.

Ah, you're right. Thanks for pointing that out. I'll fix it so the original image is preserved.

For context: Disco Science Lite currently overlays a grayscale mask on top of the vanilla lab sprite. This was originally needed to hide the blue glow from the vanilla animation, but since the base animation is now frozen, that mask is no longer necessary. I'll remove it.

Okay, I've published version 0.4.7 with a fix for the issue. Please give it a try!

Just checked the update and it looks like both issues have been fixed. The labs look much better now.
