This plugin adds 3 versions for a shader that increase contrast and add a cool atmosphere shading, making dark colors slightly blue-ish.

"Atmosphere" - the main version.
"Atmosphere (HC)" (High contrast) - crispier version
"Atmosphere (LC)" (Low contrast) - no contrast version, a bit "foggy" look.

If you have any suggestions/problems, please tell in comments. I may slightly change the color, contrast/brightness/etc. in future.
Notes:
You need to enable the shader in settings (graphics tab) after installing it.
The preview shows normal atmosphere & atmosphere HC shaders, not default shader & normal atmosphere shader.
Enjoy!

Update 3 (20.11.2022) - Minor color changes, now shaders don't affect game ui or text.
