How to use Color Difference Calculator
Calculate CIELAB DeltaE76 distance between two opaque sRGB colors. sRGB channels are linearized, transformed to XYZ using D65 white and then to Lab. The output explicitly identifies the1976 Euclidean distance method.
- Provide the input and select the documented mode or options.
- Run the tool and review its result and any limits reported below.
- Copy the text result or download a separate output file.
Good to know
- DeltaE76 is not DeltaE2000, WCAG contrast or an exact prediction of individual perception.
- Opaque sRGB hex/rgb/hsl inputs only. No display-profile, print-gamut or ambient-light modeling.
- Processing happens in this browser tab. Inputs and results are not automatically saved or uploaded.
