Drawing colors with colorsys

erik

Python offers a couple of basic color conversion tools in the colorsys module. In this snippet the hsv_to_rgb() function converts hue (the color), saturation and brightness values (all between 0 and 1) to red, green and blue values.

import colorsys

s = 50
b = 20
step = 0
brig = .5
sat = 1
for x in range(s):
    for y in range(s):
        c = colorsys.hsv_to_rgb(step/(s*s), 1, y/s)
        fill(*c)
        rect(x*b, y*b, b, b)
        step+= 1
