The colorsys module (shown in Example 9-10) contains functions to convert between RGB, YIQ (video), HLS, and HSV color values.
Example 9-10. Using the colorsys Module
File: colorsys-example-1.py import colorsys # gold r, g, b = 1.00, 0.84, 0.00 print "RGB", (r, g, b) y, i, q = colorsys.rgb_to_yiq(r, g, b) print "YIQ", (y, i, q), "=>", colorsys.yiq_to_rgb(y, i, q) h, l, s = colorsys.rgb_to_hls(r, g, b) print "HLS", (h, l, s), "=>", colorsys.hls_to_rgb(h, l, s) h, s, v = colorsys.rgb_to_hsv(r, g, b) print "HSV", (h, s, v), "=>", colorsys.hsv_to_rgb(h, s, v) RGB (1.0, 0.84, 0.0) YIQ (0.7956, 0.3648, -0.2268) => (0.9999998292, 0.8400000312, 0.0) HLS (0.14, 0.5, 1.0) => (1.0, 0.84, 0.0) HSV (0.14, 1.0, 1.0) => (1.0, 0.84, 0.0)
