Color Picker

Use a color picker to pick an arbitrary color.


Set mode='color' to show a color picker.

The return value is a (r, g, b, a) tuple, where r, g, b are integers between 0-255, and a is an integer between 0-100%.

color = view(box('Choose a color', mode='color'))
r, g, b, a = color
view(f'You chose the color `rgba({r}, {g}, {b}, {a}%)`.')


Set initial color

Set value= to set the initial color.

A color value can be:

  • #RRGGBB e.g. #ff0033
  • #RRGGBBAA e.g. #ff003388
  • #RGB e.g. #f03 (same as #ff0033)
  • #RGBA e.g. #f038 (same as #ff003388)
  • rgb(R,G,B) e.g. rgb(255, 0, 127) or rgb(100%, 0%, 50%)
  • rgba(R,G,B,A) e.g. rgb(255, 0, 127, 0.5) or rgb(100%, 0%, 50%, 50%)
  • hsl(H,S,L) e.g. hsl(348, 100%, 50%)
  • hsl(H,S,L,A) e.g. hsl(348, 100%, 50%, 0.5) or hsl(348, 100%, 50%, 50%)
  • A named color e.g. red, green, blue, etc.
  • transparent (same as rgba(0,0,0,0))

The return value, as in the previous example, is a (r, g, b, a) tuple.

color = view(box('Choose a color', mode='color', value='#a241e8'))
view(f'You chose {color}.')


Handle changes immediately

Add live to mode to handle changes immediately.

color = [162, 65, 232, 100]
while True:
    color = view(
            'Choose a color',
            mode='live color',
        f'You chose {color}.'



Set disabled=True to disable.

view(box('Choose a color', mode='color', disabled=True))
