Presets are a common feature for several Colors commands. You can find its description in Skyrius 8.1.1, „Colors Common Features“.

Posterize Levels

Here, level means number of colors per channel .

This slider and the input boxes with arrowheads allow you to set the number of levels (2-256) in each RGB channel that the tool uses to describe the active layer. The maximum total number of colors is the combination of these levels. A level to 3 will give 33 = 27 colors.
