DeltaEAlgorithm enum
The algorithms used to calculate the difference between two colors.
Values
- cie76 → const DeltaEAlgorithm
-
The 1976 formula is the first formula that related a measured color difference to a known set of CIELAB coordinates. This formula has been succeeded by the 1994 and 2000 formulas because the CIELAB space turned out to be not as perceptually uniform as intended, especially in the saturated regions. This means that this formula rates these colors too highly as opposed to other colors.
- cie94 → const DeltaEAlgorithm
-
The 1976 definition was extended to address perceptual non-uniformities, while retaining the CIELAB color space, by the introduction of application-specific weights derived from an automotive paint test's tolerance data.

- ciede2000 → const DeltaEAlgorithm
-
Since the 1994 definition did not adequately resolve the perceptual uniformity issue, the CIE refined their definition, adding five corrections:
- A hue rotation term, to deal with the problematic blue region (hue angles in the neighborhood of 275°)
- Compensation for neutral colors (the primed values in the LCh differences)
- Compensation for lightness
- Compensation for chroma
- Compensation for hue
