The best color selector？

I was just reading Björn Ottosson’s article. In it there is a summary of the various models and two new models are proposed： HSV HSL HSLuv Lab-like* NCS Okhsv Okhsl Orthogonal Lightness no no yes yes no no yes Orthogonal Chroma no no no yes partial no no Orthogonal Saturation partial no no no** no partial no Orthogonal Hue partial partial partial yes yes yes yes Simple Geometrical Shape yes yes yes no no*** yes yes Max Chroma at Edge yes no no yes no yes no Varies Smoothly y…

The provided link to Björn Ottosson blog provides detailed explanations about the color space and also he gives mathematics & algorithms

Could help anyone who want to made the implementation
