When using this mod without a resource pack (didn't try with a resource pack on) and applying night vision while it's night makes everything completely black. The blocks? Black. Mobs? Black. Items in inventory? Black. Text in options screen? Black. It looks exactly like MC-165208

The same issue appears in clear skies so you guys could maybe solve the issue together

Does this issue only occur when the Clear Skies option is enabled?

this issue occurs when:

1. clear skies without colormatic is installed
2. colormatic without clear skies is installed
3. both are installed.
   however since you can't reproduce it, it seems to be a compatibility issue with another mod so i'll have to investigate
