HSL color schemes

24Flow and its various modules make use of the HSL (Hue, Saturation and Luminosity) mode, not the classical RGB one (Red, Green and Blue). This HSL mode is especially appropriate to build colorblind friendly palettes. About 8% of males and 0.5% of females are colorblind.

As colorblind people’s retina has difficulties to differentiate the Hue (the actual color), they rely more on the Luminosity (also named brightness). The Luminosity is the key parameter when building a colorblind friendly palette.

The definition of the HSL colors is maintained in the Salesforce Custom Metadata Types.
