Summary
Four Lightness scales plotted as functions of normalized luminance. Munsell Renotation; [1] a fifth-order polynomial in Munsell Value; Hunter's rational function; [2] Square Root; [3] and Ladd and Pinney's modified cube root[4] are shown. Ladd and Pinney's modified cube root is truncated (no negative values appear).
