How do I change sun brightness and color of the sky?

As the title says. I tried it once but the changes were reversed when I restarted the mod.

1. You need to find entity level.
2. Open properties and edit level__weatherChoice.
   You need to remove any chances for weathers. Just set all weights to 0.0.
   
   
   
   
   
3. Create any weather and edit properties.

If you already added weather try to do 1 and 2. After that do restart.
