About: HWB color model

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

HWB is a cylindrical-coordinate representation of points in an RGB color model, similar to HSL and HSV. It was developed by HSV’s creator Alvy Ray Smith in 1996 to address some of the issues with HSV. HWB was designed to be more intuitive for humans to use and slightly faster to compute. The first coordinate, H (Hue), is the same as the Hue coordinate in HSL and HSV. W and B stand for Whiteness and Blackness respectively and range from 0–100% (or 0–1). The mental model is that the user can pick a main hue and then “mix” it with white and/or black to produce the desired color.

  • HWB是一种将RGB色彩模型中的点在圆柱坐标系中的表示法。類似於HSL和HSV。它是由HSV的發明者於1996年開發的，用意是解決HSV的某些問題。HWB能更直觀的使用，且能加速計算速度。 * H: 色相(Hue)，與HSL和HSV一樣，範圍是0°～360°。 * W:白色(White)，白色的濃度，範圍是0%～100%。 * B:黑色(Black)，黑色濃度，範圍是0%～100%。 HWB被應用在CSS4。 (zh)
