Choosing colors from the Color panel
You can use the Color panel to select a color and view information about the selected color. The Color panel has two viewing modes: compact and full view. In full view, both the color wheel and sliders are displayed. In compact view, only the sliders are displayed.
The Color panel in compact view
In the Color panel, you can choose a color from the Hue Ring and adjust the color from the Saturation/Value Triangle. The following information can help you adjust colors by using the Saturation/Value Triangle.
You can also set the Hue, Saturation, Value (HSV) and standard Red, Green, Blue (RGB) values for the selected color.
The Main and Additional Color swatches display in the Color panel and the toolbox. They include two overlapping swatches: the front swatch displays the selected Main color and the back swatch displays the selected Additional color.
The Additional color is used when applying more than one color, as in two-color brushstrokes, two-point gradients, and Image Hose effects. It is not what other graphics applications refer to as the "background color." In Corel Painter, the background color is the canvas color.
The Main Color and Additional Color overlapping swatches
You can preview a new color before selecting it. When you interact with the Hue Ring, the Saturation/Value triangle, or the sliders, the left half of the color swatch displays a preview of the new color and the right half shows the current color.
You can also enable the Clone Color option from the Color panel. For more information, see Cloning color.
