The combination of manual and automatic grouping methods allows you to select an object and start its color correction quickly.
Color correction is possible on the standard palette and on separate RGB and HSL channels. But an especially useful tool is the fine-tuning color in the coordinates of Hue/Lightness and Lightness/Saturation.
Moving the mouse along the palette changes the color of the selected object. We see the object of a new color on the screen at once. But if you move away the mouse from the palette the color of the object will return to the previous state. To set the color change, click on the palette, when the object is painted in the suitable color.
