wlpick

A Wayland color picker with a magnifying loupe. Captures the screen, lets you zoom in on a pixel, and copies the color to your clipboard on click. Inspired by Firefox's Eyedropper tool.

Features

• Fullscreen overlay with live magnifying loupe
• Crosshair for precise pixel targeting
• Color swatch preview with hex value
• Multiple output formats: hex, rgb, hsl
• Copies result to clipboard automatically
• Prints to stdout (pipeable)

Requirements

• A Wayland compositor with wlr-screencopy support (Sway, Hyprland, and most wlroots-based compositors)
• grim — for screen capture
• wl-clipboard — for clipboard support

sudo apt install grim wl-clipboard  # Debian/Ubuntu

Installation

From source

git clone https://github.com/BarriosXJavier/wlpick
cd wlpick
cargo install --path .

Requires Rust 1.70+. The binary lands in ~/.cargo/bin/wlpick.

Usage

wlpick                     # default: hex output, copies to clipboard
wlpick --format rgb        # output as rgb(r, g, b)
wlpick --format hsl        # output as hsl(h, s%, l%)
wlpick --no-clipboard      # print only, skip clipboard

Keybinds

Action	Input
Pick color	Left click
Cancel	Close window / Escape

Piping

Since the color is printed to stdout, you can pipe it:

# Use picked color in a script
COLOR=$(wlpick)
echo "You picked: $COLOR"

# Notify via dunst
wlpick | xargs -I{} notify-send "Picked color" {}

Output formats

Format	Example
hex (default)	#1A2B3C
rgb	rgb(26, 43, 60)
hsl	hsl(210, 40%, 17%)
