CIEDE2000 Color Difference Samples
We believe that our implementations of the CIEDE2000 color difference formula, whose source code is in the public domain, are correct and consistent across all supported programming languages to 10 decimal places.
This interactive tool generates sample data to facilitate comparisons between CIE ΔE 2000 implementations. On the other hand, the large-scale generator is used to carry out tests on a large number of color pairs.
Generator Settings
• Display the sequence of CIE ΔE2000 sample data.
• Use to calculate h_mean.
