# colorpicker
|
|
|
|
A small tool for X11 that writes the color value on your screen at the cursor
|
|
position to stdout, in RGB.
|
|
|
|
### Usage
|
|
|
|
Left click to print the pixel color, any other mouse click to quit the program.
|
|
|
|
#### One Shot
|
|
|
|
In order to just select one pixel run colorpicker with the `--one-shot` option.
|
|
The program will then quit after the first click.
|
|
|
|
#### Output Format
|
|
|
|
By default the program prints out the color in RGA format and in hexadecimal.
|
|
Here is an example:
|
|
```
|
|
R: 44, G: 190, B: 78 | Hex: #2CBE4E
|
|
```
|
|
|
|
With the help of the `--short` option you can force colorpicker to just
|
|
print out the hexadecimal value. Then you just get: `#2CBE4E`.
|
|
|
|
#### Color Preview
|
|
|
|
colorpicker allows you to show a preview of the color the currently hovered
|
|
pixel in a reactangle. This reactangle is located at the bottom left of your
|
|
screen. This comes in handy in combination with the one shot option so you
|
|
don't pick blindly a color. Just add the `--preview` option for this feature.
|
|
|
|
#### Examples
|
|
|
|
```bash
|
|
# Pick a color and put the hexadecimal value in your clipboard
|
|
$ colorpicker --short --one-shot | xsel -b
|
|
|
|
# Pick a color with preview and put the hexadecimal value in your clipboard
|
|
$ colorpicker --short --one-shot --preview | xsel -b
|
|
```
|
