篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了色相饱和度明度的简称是H,S,B还是H,S,V?相关的知识，希望对你有一定的参考价值。

H(hues)表示色相，S(saturation)表示饱和度，B（brightness）表示亮度；HSV是单纯疱疹病毒的缩写HSV主要通过直接密切接触和性接触传播。参考技术A H(hues)色相，S(saturation)饱和度，V(value）明度参考技术B HLS 是Hue(色相)、Luminance(亮度)、Saturation(饱和度)。

类似的，给定在 HSV 中 (h, s, v) 值定义的一个颜色，带有如上的 h，和分别表示饱和度和明度的 s 和 v 变化于 0 到 1 之间，在 RGB 空间中对应的 (r, g, b) 三原色可以计算为：
