Nonseparable blend modes

Hue

This mode creates a color with the hue of the source color and the saturation and luminosity of the backdrop color.

Saturation

This mode creates a color with the saturation of the source color and the hue and luminance of the backdrop color. Painting with this mode in an area of the backdrop that is a pure gray (no saturation) produces no change.

Color

This mode creates a color with the hue and saturation of the source color and the luminance of the backdrop color. This preserves the gray levels of the backdrop. It is useful for coloring monochrome images or tinting color images.

Luminosity

This mode creates a color with the luminance of the source color and the hue and saturation of the backdrop color. This produces an inverse effect to that of the 'Color' mode.
