Invoke color picker with shortcut

[blaylockbk]

VS code has a built-in color picker that is so handy for some languages but is not useable in a Python script.

Sometimes I have a variable or argument that represents a color RGB or Hex, and it would be wonderful if I could modify these with a color picker. It's probably not possible for the extension to automatically know these are colors, but it would be nice if I could manually invoke the color picker with a short cut, as discussed here microsoft/vscode#52364, and then click the color to insert it.

Color variable as RGB

my_color = (.4, .5, .3)

Color argument as a Hex value

import matplotlib.pyplot as plt
plt.plot([1,2,3,4], color="#6666ff")
