Colour adjustments are used to modify the colour of all, or a range of, pixels within a photo. Depending on the adjustment, the modification can be subtle or extreme.
Available colour adjustments include:
- Black and White—converts a colour photo to greyscale.
- Channel Mixer—adjusts the colour of a photo by modifying individual RGB channels.
- Colour Balance—adjusts the contribution of particular colours to a set tonal range.
- Gradient Map—uses the lightness value of pixels in a photo to recolour it using a specified gradient.
- HSL—shifts the hue, saturation and luminosity values of pixels in a photo.
- Lens Filter—emulates the use of a lens filter to tint the colour of the image.
- OCIO—(OpenColorIO only) provides source and destination colour space transforms.
- Recolour—converts a colour photo to monochrome using a specified tint.
- Selective Colour—subtly adjusts the colour of a photo by modifying individual RGB, CMYK and lightness channels.
- Split Toning—tints and recolours highlights and shadows.
- Threshold—converts any photo into a two-tone, black and white image based on pixel lightness.
- Vibrance—adjusts the intensity of colours within a photo.
- White Balance—removes undesirable colour casts from a photo by adjusting the 'temperature' of the light.
