相关色彩模式知识: HSV颜色空间 HSV(hue,saturation,value)颜色空间的模型对应于圆柱坐标系中的一个圆锥形子集,圆锥的顶面对应于V=1. 它包含RGB模型中的R=1,G=1,B=1 三个面,所代表的颜色较亮。色彩H由绕V轴的旋转角给定。红色对应于 角度0° ,绿色对应于角度120°,蓝色对应于角度240°。在HSV颜色模型中,每一种颜色和它的补色相差180° 。 饱和度S取值从0到1,所以圆锥顶面的半径为1。HSV颜色模型所代表的颜色域是CIE色度图的一个子集,这个 模型中饱和度为百分之百的颜色,其纯度一般小于百分之百。在圆锥的顶点(即原点)处,V=0,H和S无定义, 代表黑色。圆锥的顶面中心处S=0,V=1,H无定义,代表白色。从该点到原点代表亮度渐暗的灰色,即具有不同 灰度的灰色。对于这些点,S=0,H的值无定义。可以说,HSV模型中的V轴对应于RGB颜色空间中的主对角线。 在圆锥顶面的圆周上的颜色,V=1,S=1,这种颜色是纯色。HSV模型对应于画家(Knowledge of color patterns: HSV color space HSV (hue, saturation, value) color space model corresponds to a conical subset in cylindrical coordinate system, the corresponding top cone in V=1. which contains the RGB model of R=1, G=1, B=1 three, the color is bright. The color H is given by the rotation angle around the V axis. The red corresponds to the angle 0 degrees, the green corresponds to the angle 120 degrees, the blue corresponds to t)
