Display P3
A wide colour space now standard on modern phones, tablets and laptops, combining the DCI-P3 primaries with sRGB's white point and transfer…
Colour & Colour ManagementGamma
The non-linear relationship between stored numerical values and displayed brightness in a colour space or on a device.
Colour & Colour ManagementGamut
The complete range of colours a device, medium or colour space can produce or record.
Colour & Colour ManagementGamut Mapping
The process of converting colours from a larger space into a smaller one while preserving as much of the image's appearance as possible.
Colour & Colour ManagementHSL
A colour model describing colour by hue, saturation and lightness, widely used for targeted colour editing.
Colour & Colour ManagementHue
The attribute of a colour that gives it its name — red, green, blue — represented as a position on a circular scale.
Colour & Colour ManagementICC Profile
A standardised data file describing how a device's colour numbers relate to absolute, measurable colour.
Colour & Colour ManagementKelvin Scale
The absolute temperature scale used to state the colour of light sources and white balance settings.
Colour & Colour ManagementLightness
The perceived brightness of a colour on a scale from black to white, independent of its hue and chroma.
Colour & Colour ManagementLook-up Table (LUT)
A table mapping input colour values to output values, used to apply a colour transformation quickly and repeatably.
Colour & Colour ManagementMetamerism
The phenomenon in which two samples match under one light source but differ visibly under another.
Colour & Colour ManagementMired
A unit of reciprocal colour temperature that makes colour shifts uniform in perceptual terms, used to specify filters and gels.
Colour & Colour ManagementMixed Lighting
A scene illuminated by two or more sources of different colour temperature, which cannot all be neutralised at once.
Colour & Colour ManagementMonitor Calibration
Measuring a display with an instrument and building a profile so its output matches known standards for white point, brightness and tone…
Colour & Colour ManagementOut-of-gamut Colour
A colour present in an image that the destination device or space cannot reproduce.
Colour & Colour ManagementPerceptual Rendering Intent
A conversion strategy that compresses the entire colour range so relationships between colours are preserved, at the cost of shifting every…
Colour & Colour ManagementProPhoto RGB
A very wide colour space that encompasses almost all colours a camera can capture, including some outside human vision.
Colour & Colour ManagementRec. 2020
The very wide colour space defined for ultra-high-definition television and high dynamic range delivery.
Colour & Colour ManagementRec. 709
The colour space and transfer function standard for high-definition television, sharing its primaries with sRGB.
Colour & Colour ManagementRelative Colorimetric Intent
A conversion strategy that reproduces in-gamut colours exactly and clips out-of-gamut ones to the nearest reproducible value.
Colour & Colour ManagementRendering Intent
The strategy chosen for handling colours that fall outside the destination gamut during a colour space conversion.
Colour & Colour ManagementSaturation
The intensity or purity of a colour, from fully neutral grey to the most vivid version available.
Colour & Colour ManagementSelective Colour
An adjustment that targets one range of colours in an image while leaving the rest unchanged.
Colour & Colour ManagementSpectral Power Distribution
A plot of how much energy a light source emits at each wavelength across the visible spectrum.
