Hi everyone!

I‘ve been using the blend modes of Figma recently to try to optimize generating a color palette with different shades.

I used the blending mode ‚luminosity‘ with a certain brightness over a base color.

Now I want to code what I‘ve designed. The problem is that I don‘t know what algorithm Figma uses to make the luminosity blend mode. Does anyone know?

Most models just change the L value in the HSL which gives me different perceived brightness since the H (Hue) seems brighter for yellow compared to blue or red.

In Figma, the brightness seems always the same no matter what base color I use underneath. I want to recreate exactly that.

Thank you and best regards!
