Two Keys

The color of the first color pad will be accepted as key black. In the second color pad you set a color, which will be accepted as key white. As a result, all colors, which are darker than key black, will be shifted in the side of black color, and all colors, which are lighter than key white, will be shifted in the side of white color.

It is also possible to set one key colors, either it is black, or white. For example, if you will set only key black, dark colors will be shifted in the side of black color, and all light colors remain untouched.

When setting key colors, take into account, that the lighter you set key black, the darker the image will be, and the darker you set key white, the lighter image will be.
