Brightness
Adds the values of all color components.

Regulates the overall contrast of the texture. A value greater than 0 raises the contrast, a value less
than 0 lowers the contrast. A value of -100% produces a completely neutral gray. A value of 100%
gives full contrast between complete saturation and no saturation.
Gamma
Regulates the mid-tones. Lesser values darken the mid-tones, greater values brighten them up.
