I wrote a plugin to cycle between `hex`, `rgb` and `hsl` color formats
I really liked the idea of this plugin, but I wasn't too much of a fan of using a python dependency. So it inspired me to put this together: https://github.com/amadeus/vim-convert-color-to It converts between `rgb`, `hsl` and `hex` (including transparent colors) and is all written in viml.

February 23, 2019HEX, RGB or HSL?
I use hex, unless I also use an alpha channel, then I use rgba(). Why? I've used it for years, before rgb() was available. More on reddit.com

July 1, 2014How do I convert RGB to HSL in Python?
Use `colorsys.rgb_to_hls(r, g, b)` with values normalized to 0–1. Note the return order is (H, L, S) — hue, lightness, saturation — not (H, S, L). Multiply H by 360 for degrees, L and S by 100 for percentages. Example: `colorsys.rgb_to_hls(26/255, 115/255, 232/255)` returns `(0.603, 0.506, 0.798)` → H=217°, L=51%, S=80%.

How do I convert hex to RGB in Python?
Remove the `#` prefix, then slice the six-character string into three two-character substrings and convert each with `int(s, 16)`. Example: `hex = '#1a73e8'; rgb = tuple(int(hex.lstrip('#')[i:i+2], 16) for i in (0, 2, 4))` returns `(26, 115, 232)`. For 3-digit shorthand hex, expand each digit before parsing.

How do I generate a random hex color in Python?
Use `'#{:06x}'.format(random.randint(0, 0xFFFFFF))` for a random hex color. For a vivid random color, randomize only the hue: convert a random HSV value `(random.random(), 0.7, 0.9)` to RGB with `colorsys.hsv_to_rgb()`, then to hex. The fixed saturation/value ensures bright, readable output.

Python methods to convert colors between RGB, HSV and HSL · GitHub
@mathebox & @ArtemBernatskyy, According to https://en.wikipedia.org/wiki/HSL_and_HSV, add l = (high + low) / 2, and not low.

I believe that this does what you are looking for:
h = input('Enter hex: ').lstrip('#')
print('RGB =', tuple(int(h[i:i+2], 16) for i in (0, 2, 4)))
(The above was written for Python 3)
Sample run:
Enter hex: #B4FBB8
RGB = (180, 251, 184)
Writing to a file
To write to a file with handle fhandle while preserving the formatting:
fhandle.write('RGB = {}'.format( tuple(int(h[i:i+2], 16) for i in (0, 2, 4)) ))

You can use ImageColor from Pillow.
>>> from PIL import ImageColor
>>> ImageColor.getcolor("#23a9dd", "RGB")
