If a fragment of the image is divided into many segments, they can be easily grouped. This can be done manually. But the program also includes highly effective tools for automatic grouping of segments.
Color correction is possible on a standard palette, separate RGB and HSL channels, and control elements for fine color tuning.
The color of the selected fragment changes during the fly of your mouse. When the mouse moves over one of the controls, you can see the color change. But if you move away the mouse, the fragment's color will return to the previous state. To set the color change, click on the control element and the object is painted in the suitable color.
