Munsell's amazing! This similar to Munsell, but where his space was based on specific, literal sample colors, this one is based on a mathematical model -- but the experiments to determine that model were remarkably similar to his!
The core model is CIE Lab: https://en.wikipedia.org/wiki/CIELAB_color_space https://en.wikipedia.org/wiki/CIELAB_color_space
The a and b* parameters of that model are not totally intuitive, though; luckily, the same space expressed in polar coordinates has parameters that map really well to the same hue, chroma, and lightness that Munsell organized with.
- Daub 6y agoI have used Lab space in Photoshop a bit. You are right... it is a relative to Munsell. Lab has one or two very particular uses in color adjustment. For example... as lightness is completely separate to chromacity, it is a very agreeable space for lightness and saturation adjustments. It is also great for demonstrating to students how the perceptual Lightness value of a hue differs to the lightness value indicated by a desaturation in simple RGB space.
