## Python – Convert HSV to RGB

To convert HSV color values to RGB color values in Python, import `colorsys` library, call `hsv_to_rgb()` function, and pass the Hue, Saturation, and Value values as arguments.

`hsv_to_rgb()` function takes Hue, Saturation, and Value values as arguments, and returns a tuple containing Red, Blue, and Green values.

The Hue, Saturation, and Value values must be normalised to the range [0, 1] prior to conversion for input to `hsv_to_rgb()` function.

### Examples

In the following program, we take a HSV value and convert it to an RGB value.

Python Program

``````import colorsys

(h, s, v) = (0.2, 0.4, 0.4)
(r, g, b) = colorsys.hsv_to_rgb(h, s, v)
print('RGB :', r, g, b)``````
Run

Output

``RGB : 0.368 0.4 0.24``

#### Convert HSV to RGB with values in 8-bit Ranges

In the following program, we are getting HSV values in the range specified in the below table, and we shall convert it to RGB values to the ranges mentioned below.

Python Program

``````import colorsys

#input
(h, s, v) = (142, 244, 85)
#normalize
(h, s, v) = (h / 255, s / 255, v / 179)
#convert to RGB
(r, g, b) = colorsys.hsv_to_rgb(h, s, v)
#expand RGB range
(r, g, b) = (int(r * 255), int(g * 255), int(b * 255))
print('RGB :', r, g, b)``````
Run

Output

``RGB : 5 81 121``

### Summary

In this Python Tutorial, we learned how to convert a HSV color value to an RGB color value, using `colorsys` library.
