Color Palette¶
Use a color palette to pick one color from a group of colors.
Basic¶
Set options=
with mode='color'
to show a color palette.
The option's value
must be a valid color in one of the formats described in the previous example.
Unlike the Color Picker, the Color Palette returns the value
of the chosen option, and not a (r,g,b,a)
tuple.
color = view(box('Choose a color', mode='color', options=[
option('#ff0000', 'Red'),
option('#00ff00', 'Green'),
option('#0000ff', 'Blue'),
option('#ffff00', 'Yellow'),
option('#00ffff', 'Cyan'),
option('#ff00ff', 'Magenta'),
]))
view(f'You chose {color}.')
Set initial color¶
Set value=
to pre-select an option having that color value.
color = view(box('Choose a color', mode='color', value='#0000ff', options=[
option('#ff0000', 'Red'),
option('#00ff00', 'Green'),
option('#0000ff', 'Blue'),
option('#ffff00', 'Yellow'),
option('#00ffff', 'Cyan'),
option('#ff00ff', 'Magenta'),
]))
view(f'You chose {color}.')
Mark colors as selected¶
Alternatively, set selected=True
to pre-select a color in the palette.
color = view(box('Choose a color', mode='color', options=[
option('#ff0000', 'Red'),
option('#00ff00', 'Green'),
option('#0000ff', 'Blue', selected=True),
option('#ffff00', 'Yellow'),
option('#00ffff', 'Cyan'),
option('#ff00ff', 'Magenta'),
]))
view(f'You chose {color}.')
Handle changes immediately¶
Add live
to mode
to handle changes immediately.
color = '#0000ff'
while True:
color = view(
box(
'Choose a color',
mode='live color',
value=color,
options=[
option('#ff0000', 'Red'),
option('#00ff00', 'Green'),
option('#0000ff', 'Blue'),
option('#ffff00', 'Yellow'),
option('#00ffff', 'Cyan'),
option('#ff00ff', 'Magenta'),
],
),
f'You chose {color}.'
)
Disable¶
Set disabled=True
to disable.
