epick

Color picker for creating harmonic color palettes that works on Linux, Windows, macOS and web.

Get it

You can checkout the web demo over here or get a native binary from the GitHub release page.

If you happen to use Arch Linux you can grab epick from AUR using your favorite package manager:

$ paru -S epick

Build

Install required libraries (only required on Linux):

$ apt-get install libxcb-render0-dev libxcb-shape0-dev libxcb-xfixes0-dev libxkbcommon-dev

To manually build epick you'll need the latest Rust with cargo. To build the project run:

$ make

To start the web version locally run:

$ make start_web

This will build the WASM files and start a simple http server listening at 127.0.0.1:8080.

To build without make checkout the build instructions in the Makefile

Demo

The gif might be outdated, to checkout the latest build of master branch head over to the web demo.

Keyboard shortcuts

Here are some handy shortcuts to enhance the usage of epick:

• Only supported with screen picker:
  • z to display zoomed window
  • p to pick a color from under the cursor
  • s to save a color from under the cursor
• Other:
  • h toggle side panel

Custom color format

To fully customize the way the colors are presented textually on the screen and the way they are copied to clipboard, a simple formatting language has been introduced that resembles the syntax of rust formatting macros. Here is a simple example of such a formatting string:

"{r} {g} {b}"
// Same as
"{ r } {  g} {    b     }"

Above example shows how to display a value of a field. The name of the field is enclosed in curly braces and can contain multiple white space characters following the opening brace and preceeding the closing brace. This format string will print red, green and blue values of the color in the 0.0 ..= 1.0 range.

To specify the precision of a floating point number:

"{r:.2} {g:.0} {b:.4}"

To display a value in decimal, octal, hex or uppercase hex respectively:

"{lab_l:d} {r255:o} {g255:x} {b255:X}"

Using this flags on floating values will automatically truncate the fractional part and treat the number as an integer.
