HSV to RGB Color Conversion

Is there a way to convert HSV color arguments to RGB type color arguments using pygame modules in python? I tried the following code, but it returns ridiculous values.

import colorsys
test_color = colorsys.hsv_to_rgb(359, 100, 100)
print(test_color)

and this code returns the following nonsense

(100, -9900.0, -9900.0)

This obviously isn't RGB. What am I doing wrong?

Solution

  • That function expects decimal for s (saturation) and v (value), not percent. Divide by 100.

    >>> import colorsys

# Using percent, incorrect
>>> test_color = colorsys.hsv_to_rgb(359,100,100)
>>> test_color
(100, -9900.0, -9900.0)

# Using decimal, correct
>>> test_color = colorsys.hsv_to_rgb(1,1,1)
>>> test_color
(1, 0.0, 0.0)

    If you would like the non-normalized RGB tuple, here is a function to wrap the colorsys function.

    def hsv2rgb(h,s,v):
    return tuple(round(i * 255) for i in colorsys.hsv_to_rgb(h,s,v))

    Example functionality

    >>> hsv2rgb(0.5,0.5,0.5)
(64, 128, 128)
