RECOLOR is a drawing tool capable of replacing colors on the affected pixels.
RECOLOR is by default used with the BRUSH tool.
Simply select the color you want to replace, the Nahradit, and the color you want to replace the Nahradit with in the Fill section. Alternatively, Clicked pixel can be selected to replace the color of the clicked pixel anywhere in the image to your Fill color.
Tolerance parameter controls how different may the pixels be to be considered close enough to be painted.
The check-boxes near Size, Blur, and Flow control whether the tablet pen pressure should influence the actual value set in these boxes.
When the SHIFT key is held down, you can draw lines whilst replacing the color you specify.
