This example demonstrates how to convert between a color value in RGB (three integer values in the range 0 to 255 representing red, green, and blue) and HSB (three floating point values in the range 0 to 1.0 representing hue, saturation, and brightne
def rgb2hsv(r, g, b): r, g, b = r/255.0, g/255.0, b/255.0 mx = max(r, g, b) mn = min(r, g, b) m = mx-mn if mx == mn: h = 0 elif mx == r: if g >= b: h = ((g-b)/m)*60 else: h = ((g
