Gammabright - Tweak Mod For Minecraft 1.12.2, 1.11.2, 1.10.2

Gammabright 1.12.2 allows you to change the brightness of frames. When you click on the button (Configurable in binds) this customizes the gamut, and the main feature is that it affects blocks and mobs, for example, highlighting them several times.

It is also worth noting that the option changes the same value as the default brightness setting in normal Minecraft, but on a much larger scale. Now you can make the game much brighter or darker, which is very useful in very dark places.
