Issue description

Whenever using complementary shaders v4.7.2 alongside shimmer, dark, unlit surfaces gain so much contrast that it looks like if the color range was greatly decreased. Bright, well-lit blocks on the other hand look perfectly fine. After switching to any other shaderpack, even including very similar complementary reimagined, the issues disappear.

This is with complementary 4.7.2

This is with complementary reimagined

Steps to reproduce

1. Launch the game with both iris and shimmer installed
2. Enable Complementary Shaders v4.7.2 and go to a dark area
3. Done
