HSL和HSV色彩空间 HSL and HSV

(重定向自Color spindle)
HSL(a~d)和HSV(e~h)。上半部分(a、e):两者的3D模型截面。下半部分:将模型中三个参数的其中之一固定为常量,其它两个参数的图像。
HSV色轮允许用户快速的选择众多颜色。
HSV模型的圆锥表示适合于在一个单一物体中展示整个HSV色彩空间。
HSL和HSV色彩空间比较。

HSLHSV都是一种将RGB色彩模型中的点在圆柱坐标系中的表示法。这两种表示法试图做到比RGB基于笛卡尔坐标系的几何结构更加直观。

HSL即色相、饱和度、亮度(英语:Hue, Saturation, Lightness),又称HSL。HSV即色相、饱和度、明度(英语:Hue, Saturation, Value),又称HSB,其中B即英语:Brightness

HSL和HSV二者都把颜色描述在圆柱坐标系内的点,这个圆柱的中心轴取值为自底部的黑色到顶部的白色而在它们中间的是灰色,绕这个轴的角度对应于“色相”,到这个轴的距离对应于“饱和度”,而沿着这个轴的高度对应于“亮度”,“色调”或“明度”。

HSL and HSV HSL和HSV色彩空间

(重定向自Color spindle)
Fig. 1. HSL (a–d) and HSV (e–h). Above (a, e): cut-away 3D models of each. Below: two-dimensional plots showing two of a model’s three parameters at once, holding the other constant: cylindrical shells (b, f) of constant saturation, in this case the outside surface of each cylinder; horizontal cross-sections (c, g) of constant HSL lightness or HSV value, in this case the slices halfway down each cylinder; and rectangular vertical cross-sections (d, h) of constant hue, in this case of hues 0° red and its complement 180° cyan.
Fig. 2a. HSL cylinderFig. 2b. HSV cylinder
Fig. 3a–b. If we plot hue and (a) HSL lightness or (b) HSV value against chroma rather than saturation, the resulting solid is a bicone or cone, respectively, not a cylinder. Such diagrams often claim to represent HSL or HSV directly, with the chroma dimension deceptively labeled

HSL and HSV are the two most common cylindrical-coordinate representations of points in an RGB color model. The two representations rearrange the geometry of RGB in an attempt to be more intuitive and **** relevant than the cartesian (cube) representation. Developed in the 1970s for computer graphics applications, HSL and HSV are used today in color pickers, in image editing software, and less commonly in image analysis and computer vision.
