Choose blending modes from the pop-up menu in the Painting Tool Options palette. The various paint modes in combination with opacity/pressue settings have a selective control on which pixels are affected when you use the painting and editing tools. The result is more of a blending of the paint colour and the colour of the base pixels than simply one colour replacing another.
Produces a grainy, chalk-like effect. Not all pixels are coloured as you drag across the image, leaving gaps and holes in the storke. Reduce the Opacity setting to control the effect.
Makes pixels transparent. You can only access this mode on a layer with the Lock Transparency option deselected. Available for the Brush, Paint Bucket, Pencil and Line tools.
Only available when you are working on a layer with a transparent background. Make sure Lock Transparency is deselected for the layer. Use behind to paint behind the existing pixels on a layer. Paint appears in the transparent areas, but does not affect the existing pixels.
Applies the paint colour to pixels that are lighter than the paint colour – doesn’t change pixels darker than the paint colour.
Combines the colour you are painting with the colour of the pixels you drag across, to produce a colour that is darker than the original colours.
Darkens the base colour by increasing the contrast in base colour pixels, depending on the contrast in base colour pixels, depending on the blend colour. More pronounced when paint colour is dark. Blending with white has no effect.
Darkens the base colour by decreasing brightnessdepending on the blend colour used. Blending with white has no effect.
Replaces pixels darker than the paint colour, but does not change pixels lighter than the paint colour.
Produces the opposite effect to Multiply. It multiplies the opposite of the original colour by the painting colour and has the effect of lightening the pixels.
Brightnes the base colour by deceasing contrast. More pronounced when the paint colour is light. Blending with black has no effect.
Brightnes the base colour by increasing the brightness depending on the blend colour. Blending with black has no effect.
This increases the contrast and saturation, combining the foreground colour with the pixels you drag across. Highlights and shadows in the base colour are preserved.
Creates a soft lighting effect. Lightens colours if the painting colour is lighter than 50% grey, darkens colours if the painting colour is darker than 50% grey.
Multiplies (darkens) or screens (lightens) pixels, depending on the paint colour, and tends to increase contrast.
Burns or Dodges base pixel colours by increasing or decreasing contrast depending on the blend colour.
Burns Dodges base pixel colours by increasing or decreasing brightness depending on the blend colour.
Replaces base colour pixels depending on whether the blend colour is lighter or darker than 50% grey.
It looks at the brightness of pixels and the paint colour, then subtracts paint brightness from pixel brightness. Depending on the result, it inverts the pixels.
The result is similar to difference, but with lower contrast.
In colour images, applies the hue (colour) of the paint, without affecting the saturation or luminosity of the base pixels.
Changes the saturation of pixels based on the saturation of the blend colour, but does not affect hue or luminosity.
Changes the relative lightness or darkness of the pixels without affecting their hue/saturation.
Applies the hue and saturation of the blend colour, but does not affect the luminosity of the base pixels.
