Quick method to change global characteristics of the Sub-Material::

Contrast
Brightness
Color Balance
Hue/Luminance/Saturation

Usage of this material in the first time aimed for quick color tuning. Especially when exist material (with the complex Sub-Texture system, with reflection/refrction maps, bumps etc.) which is entirely satisfied 3D designer, but something wants to be changed in that (and besides to do this demands as fast as possible). For example: to change a little bit the color hue, to decrease or increase material brightness. To add yellow or other base color from RGB-CMY color model. To do material more contrast, to change color saturation and etc.

That correctings of Sub-Material do not pretend on physical exactness, but they provide to quicken color tuning process.
