Normal4026531841 Selects the source colour, ignoring the backdrop.
Multiply4026531842 Multiplies the backdrop and source colour values. The result colour is always at least as dark as either of the two constituent colours. Multiplying any colour with black produces black; multiplying with white leaves the original colour unchanged. Painting successive overlapping objects with a colour other than black or white produces progressively darker colours.
Screen4026531844 Multiplies the complements of the backdrop and source colour values, then complements the result. The result colour is always at least as light as either of the two constituent colours. Screening any colour with white produces white; screening with black leaves the original colour unchanged. The effect is similar to projecting multiple photographic slides simultaneously onto a single screen.
Overlay4026531848 Multiplies or screens the colours, depending on the backdrop colour value. Source colours overlay the backdrop while preserving its highlights and shadows. The backdrop colour is not replaced but is mixed with the source colour to reflect the lightness or darkness of the backdrop
Darken4026531856 Selects the darker of the backdrop and source colours. The backdrop is replaced with the source where the source is darker; otherwise, it is left unchanged.
Lighten4026531872 Selects the lighter of the backdrop and source colours. The backdrop is replaced with the source where the source is lighter; otherwise, it is left unchanged.
ColorDodge4026531904 Brightens the backdrop colour to reflect the source colour. Painting with black produces no changes.
ColorBurn4026531968 Darkens the backdrop colour to reflect the source colour. Painting with white produces no change.
HardLight4026532096 Multiplies or screens the colours, depending on the source colour value. The effect is similar to shining a harsh spotlight on the backdrop.
SoftLight4026532352 Darkens or lightens the colours, depending on the source colour value. The effect is similar to shining a diffused spotlight on the backdrop.
Difference4026532864 Subtracts the darker of the two constituent colours from the lighter colour: Painting with white inverts the backdrop colour; painting with black produces no change
Exclusion4026533888 Produces an effect similar to that of the Difference mode but lower in contrast. Painting with white inverts the backdrop colour; painting with black produces no change.
Hue4096 Creates a colour with the hue of the source colour and the saturation and luminosity of the backdrop colour.
Saturation8192 Creates a colour with the saturation of the source colour and the hue and luminosity of the backdrop colour. Painting with this mode in an area of the backdrop that is a pure gray (no saturation) produces no change.
Color16384 Creates a colour with the hue and saturation of the source colour and the luminosity of the backdrop colour. This preserves the gray levels of the backdrop and is useful for colouring monochrome images or tinting colour images.
Luminocity32768 Creates a colour with the luminosity of the source colour and the hue and saturation of the backdrop colour. This produces an inverse effect to that of the Color mode.
