The **`colorsys.rgb_to_hls(r, g, b)` function** converts #key# **RGB**: Red Green Blue #key# coordinates to #key# **HLS**: Hue Lightness Saturation #key# coordinates. The `hls` color scale is a re-coding of the `rgb` color scale. We generally use this to indite variants of a color by simply increasing or decreasing the Hue, Lightness, or Saturation of the color. 



## Declaration
The `colorsys` module stores the definition of the `rgb_to_hls()` function. We can import the `colorsys` module using the following code:

```python3
import colorsys

colorsys.rgb_to_hls(r, g, b)
```
`r`, `g`, and `b` can have any value between 0 and 1 inclusive.

## Code
The following code snippet demonstrates the use of `rgb_to_hls()`:


import colorsys

if __name__ == '__main__':
  r = 132
  g = 24
  b = 100

  ## normalizing values to get value between 0 and 1
  r = r/255
  g = g/255
  b = b/255

  h, l, s = colorsys.rgb_to_hls(r, g, b)

  print('RGB:-')
  print('r: ' + str(r) + '\ng: ' + str(g) + '\nb: ' + str(b))
  print('\nHLS:-')
  print('h: ' + str(h) + '\nl: ' + str(l) + '\ns: ' + str(s))
