✨}

farge is command line tool to select pixel on the screen and return the value of the color in either HEX or RGB format. The color code is automatically saved to the clipboard.

This tool works on X11 and Wayland.

Dependencies

bash
imagemagick
feh (Other: mpv or sxiv, but you must specify it using the --image-viewer flag)

   --stdout              output the color value to stdout
   --version             show the version of farge you are using

Tips

It would be smart to bind farge to a keybinding. Here is an example for i3wm users:

bindsym $mod+Shift+f --release exec farge

If you use a window manager, you can assign rules the windows so they are always floating. For i3wm user, put this in your config:

# Let the windows created by Farge be floating
for_window [instance="Farge"] floating enable

Some errors in colorpicker?

Colorpicker works fine on my pc, but farge doesn't seem to do anything. When I try to run farge, it outputs

(colorpicker:150836): Gdk-CRITICAL **: 11:19:12.888: IA__gdk_screen_get_root_window: assertion 'GDK_IS_SCREEN (screen)' failed

(colorpicker:150836): Gdk-CRITICAL **: 11:19:12.888: IA__gdk_cursor_new_for_display: assertion 'GDK_IS_DISPLAY (display)' failed

(colorpicker:150836): Gdk-CRITICAL **: 11:19:12.888: IA__gdk_pointer_grab: assertion 'window != NULL' failed

to the console, and doesn't exit afterwards. I think gdk has something to do with gnome, which isn't installed on my system but I don't see why farge would depend on gnome. I run x11 with compton and i3 on arch if it helps.

Enable support for Wayland

I would request you to make this tool also work for Wayland . Grim is imagepicker can also be used as alternative for Colorpicker . The command grim -g "$(slurp -p)" -t ppm - | convert - -format '%[pixel:p{0,0}]' txt:-
picks color in wayland. It would be glad to see Wayland support as Wayland is future.

Add gpick as a alternative colorpicker

Hey @sdushantha

Turns out this was a simple addition, so I went ahead and implemented it myself. Let me know if I should change anything; the only thing I'm unsure of in terms of implementation is the dependency check. It works, but I'm not sure if you have a better idea in mind.

Ensure that the color code is readable on dark color background.

Love the tool!

Now if you color pick a black(or dark) color, the hex code is not readable. The script should detect the contrast ratio, and change the text color accordingly.

No colorcode text on preview

Installed through AUR in i3wm. Installed dependencies (using feh) in readme for X11. I am only seeing the color in the preview. I notice in the AUR package colorpicker-ym1234-git is mentioned as an optional dependency. I was not sure if this is needed to output the color in feh. I tried also with this particular colorpicker package with the same result. I'm not sure whether this is an issue or I just overlooked something.

macOS Support Proof of Concept

If you're interested I could create a PR for macOS support or you could add if you have access to a mac. I figured it may be better to include this into a single tool.

macOS Reqs: hammerspoon w/ cli interface installed. Though it might be possible to remove this with a little work.

Proof of Concept:

# NOTE:  Heavily inspired by https://apple.stackexchange.com/questions/87801/how-to-get-color-of-pixel-in-coordinates-123-456-in-screen/280851#280851

get_pixel_color () {

  # Use hammer spoon to get mouse x,y coords
  X=$(hs -A -c "hs.mouse.absolutePosition()['x']") 
  Y=$(hs -A -c "hs.mouse.absolutePosition()['y']")

  # Screenshot pixel at mouse coords save to $TMPDIR
  # HEX Dump and grab color 
  # NOTE: This will require security and privacy permissions to capture the screen 
    # Testing against known hex colors does not reproduce the same hex, but
    # it does produce the color on the screen. Maybe a difference in color profiles
    # or colorspace. Maybe someone that knows maybe how to convert srbg to whatever can 
    # resolve this issue.
  COLOR=$(
    screencapture -R $X,$Y,1,1 -t bmp $TMPDIR/pixel_color.bmp
    xxd -p -l 3 -s 54 $TMPDIR/pixel_color.bmp |
    sed 's/\(..\)\(..\)\(..\)/\3\2\1/'
  )
  
  # Copy Color to Clipboard
  echo "#$COLOR" | pbcopy

  # Use applescript to display a native OS notification 
  # TODO: This could be improved with imagemagick and hammerspoon 
  osascript -e '
    on run argv
      display notification "#" & item 1 of argv
    end run
  ' $COLOR
}

Can I change the font for rendering? helvetica

Can I change the font that is used for rendering in the default farge command. I get the following error:

/usr/bin/farge: line 104: bc: command not found
/usr/bin/farge: line 104: [: : integer expression expected
convert: unable to read font `helvetica' @ error/annotate.c/RenderFreetype/1425.

I don't think I have the helvetica font installed and would like to change it.

Thank you!
