Measuring colour differences
Thanks to the CIELab space, it is possible to compare and quantify the colorimetric difference between two colours:
By the colour difference on the redgreen axis Δa*
By the colour difference on the yellow-blue axis Δb*
By the difference in lightness ΔL*
By the difference in saturation ΔC*
By the difference in tint ΔH* (from the angular difference Δh between two colours)

Finally, ΔE represents the total colorimetric difference between a standard and a sample and is calculated using the different values cited previously.
