H指hue（色相）、S指saturation（飽和度）、L指lightness（亮度）、V指value(色調(diào))、B指brightness（明度）。
色相（H）是色彩的基本屬性，就是平常所說的顏色名稱，如紅色、黃色等。
飽和度（S）是指色彩的純度，越高色彩越純，低則逐漸變灰，取0-100%的數(shù)值。
明度（V），亮度（B），取0-100%。
0度: 紅色，RGB:(255, 0, 0), 255:R, 0:B，G+　　
60度: 黃色，RGB:(255,255, 0)，255:G, 0:B, R-　　
120度: 綠色，RGB:( 0,255, 0)，255:G, 0:R，B+　　
180度: 青色，RGB:( 0,255,255)，255:B, 0:R，G-　　
240度: 藍(lán)色，RGB:( 0, 0,255)，255:B, 0:G，R+　　
300度: 紫色，RGB:(255, 0,255)，255:R, 0:G，B-　　
360度: 紅色，RGB:(255, 0, 0)，255:R, 0:B，G+
RGB轉(zhuǎn)化到HSV的算法
　　　 max=max(R,G,B)
　　　 min=min(R,G,B)
　　 if R = max, H = (G-B)/(max-min)
　　　 if G = max, H = 2 + (B-R)/(max-min)
　　　 if B = max, H = 4 + (R-G)/(max-min)
　　　 H = H * 60
　　　 if H < 0, H = H + 360
