About

Python implementation of CIEDE2000 color difference calculation based on this paper:

The CIEDE2000 Color-Difference Formula: Implementation Notes, Supplementary Test Data, and Mathematical Observations.

Use this BibTeX to cite: BibTeX @article{Sharma2005TheObservations, title = {{The CIEDE2000 color-difference formula: Implementation notes, supplementary test data, and mathematical observations}}, year = {2005}, journal = {Color Research {\&} Application}, author = {Sharma, Gaurav and Wu, Wencheng and Dalal, Edul N}, number = {1}, month = {2}, pages = {21--30}, volume = {30}, publisher = {Wiley Subscription Services, Inc., A Wiley Company}, url = {http://dx.doi.org/10.1002/col.20070}, doi = {10.1002/col.20070}, issn = {1520-6378}, keywords = {CIE, CIE94, CIEDE2000, CIELAB, CMC, color-difference metrics} }

Install

pip install pyciede2000

Usage

```python from pyciede2000 import ciede2000

res = ciede2000((50.0000,2.6772,-79.7751), (50.0000,0.0000,-82.7485))

print(res) ```

ciede2000 accepts two color values as tuples in Lab representation. Also supports optional keyword parameters for para-metric weighting factor k_L, k_C and k_H.

Output format

ciede2000() returns a dict with all significant fields in CIEDE2000 calculation.

python res = { "a_1_dash": a_1_dash, "a_2_dash": a_2_dash, "C_1_dash": C_1_dash, "C_2_dash": C_2_dash, "h_1_dash": h_1_dash, "h_2_dash": h_2_dash, "h_bar_dash": h_bar_dash, "G": G, "T": T, "S_L": S_L, "S_H": S_H, "S_C": S_C, "R_T": R_T, "delta_E_00": delta_E_00 }

You might be only interested in the final delta value, delta_E_00.

print(res['delta_E_00'])
