Colormatic bugs out visually when the gamma is set above 1.0 (Bright in the settings GUI). This is a problem because many people play with a higher gamma. I play with 2.0 (200% in the settings GUI).

Cause of issue #52.

I have identified and fixed the issue in my fork. Would you like to submit a PR?

Brightness above 100% is unsupported in vanilla Minecraft and can lead to glitches.

If you want me to not use Colormatic, okay! I'll go find a different mod.
