otter-pick - Otter Shell

otter-pick samples a pixel from the screen. It opens a frozen overlay with a magnifying loupe. Click to copy hex, RGB, and OKLCH. Pass --x and --y when you want scripted sampling instead.

Usage

Run otter-pick with no arguments for the interactive overlay. Pass --x and --y to sample a screen coordinate. If you pass only one, the other defaults to the center of the captured area.

otter-pick                       # frozen overlay, loupe: click to copy hex
otter-pick --x 120 --y 80        # sample global Wayland coordinate
otter-pick --x -10 --y 80        # negative coords work for left-of-primary outputs
otter-pick --loupe --x 1 --y 2   # print 5x5 ANSI loupe for scripted sampling
otter-pick --no-copy             # print values only, no clipboard
otter-pick --hex '#336699'       # offline conversion / test

Output

otter-pick prints the sampled color in three formats, one per line.

#336699
rgb(51, 102, 153)
oklch(44.9% 0.083 249.1)

Configuration

otter-pick reads ~/.config/otter-shell/otter-pick.conf.

copy = true
loupe = false

copy: set to false to skip clipboard writes by default
loupe: set to true to always print the ANSI loupe when you sample with --x and --y

Requires ext-image-copy-capture-v1 from the compositor, with wlr screencopy as a fallback. The loupe uses the same capture path as otter-screenshot.
