Readme
An extensive color picker for the terminal
Cpick is an interactive color picker in the terminal. You can run Cpick in any true color terminal, and you can see thousands of unique colors, either from preset values or gradients. Each color has its own formats in many different forms, including RGB, HSV, CMYK, and more.
Cpick depends on Tcell and Colors.
Cpick also uses Cview. However, Cview currently has a feature where the table cells are drawn with a required space in between cells, which ruins the aesthetic of Cpick. In order to fix this, a forked version of Cview is used within the Cpick package that has the required fixes. This may lead to bugs and issues in older versions of Cview that are not able to be readily fixed until Cview adopts required features.
To include the Cpick package in your own Golang application, include the line import "github.com/ethanbaker/cpick".
To make a command based on the package, run go install in the cmd/cpick directory. Command usage can be found in the documentation. If you have difficulties compiling and installing the application, follow these comprehensive steps in the official Golang documentation.
Cpick also utilizes cmdtab, which offers tab completion for Cpick. If you wish to enable tab completion, add the line complete -C cpick cpick to your ~/.bashrc file.
Visit the AUR page to download Cpick to your arch system. If you don't know how to download a package from the Arch User Repository, you can follow directions from the Arch wiki.

Cpick can be used to select any color and output the corresponding color format. For example, entering the command cpick hex will output a hexadecimal color (ex: #123abc) when a color is selected. Many different color formats exist, such as ansi escape sequences, rgb values, or even color names.
For more examples, please refer to the documentation.
If you are looking for a simplified version, check out the docs. Here is a more in-depth explanation.
You can also see a minified help version by pressing backtick (`) while the Cpick application is running.
In Cpick, there are two main screens: the hue screen and the saturation-value screen.
The hue screen is the first screen that pops up. It contains a hue slider present at the top, two color tint previews on the left, and a table of different preset or custom colors at the bottom.
The saturation-value screen is the screen that pops up once you press enter to select a color on the hue screen. It contains one large color gradient in the center and two color tint previews on the right.
On the hue screen, you initially start off on the hue slider. This is where you can select a specific hue by navigating the table, either using h and l (from vim) or the left and right arrow keys. If you press enter, you will be moved to the saturation-value screen with the table representing the hue you chose. You can also press space to move to the listed colors at the bottom of the hue screen.
For the listed color table on the hue screen, you can navigate it using the standard vim keys (h, j, k, l) or the arrow keys. If you press enter on a selected color, you will be taken to the saturation-value screen and the color you selected will automatically be selected on the big color gradient table. You can also switch between color types by pressing c to go forward a page and C to go back.
In addition, you can press ? to open up a search menu. Here you can search for a specific color or keyword. You can press N to go to the next selection and n to go to the previous selection, just like in vim.
On the saturation-value screen, you can move about the screen using the standard vim keys (h, j, k, l) or the arrow keys. Once on a desired color, press enter to select it.
In addition, you can press g to go to the start of the table (top-left most cell) or G to go to the end of the table (bottom-right most cell).
You can press 'q' or Escape to exit the application at any point, except in the search screen (Escape brings you back to the hue screen and 'q' is treated as a normal letter).
In Cpick, you can add custom colors that can come up on the color pages. You can add JSON files that hold the colors in 3 ways.
Wherever you are running Cpick, you can provide a local colors.json file (file would have the path ./colors.json from wherever Cpick is being run). This has the highest priority.
In the ~/.config directory, you can create a cpick directory that can contain the colors.json file (file would have the path ~/.config/cpick/colors.json). This has a lower priority than a local file but a higher priority than a ./cpick directory.
In your home directory, you can create a .cpick directory that can contain the colors.json file (file would have the path ~/.cpick/colors.json). This has the lowest priority.
The colors.json file has a very strict format.
{
"colorList": [
{
"name": "COLOR NAME 1",
"colors": []
},
{
"name": "COLOR NAME 2",
"colors": []
},
{
"name": "COLOR NAME 3",
"colors": []
}
]
}
Each color type consists of an object with a name and colors key. The name key consists of what color type the colors provided are, such as CSS, Solarized, or XTERM. The colors key holds all of the colors that will be previewed when Cpick is run. All of the different color types are in the colorList array.
An individual color is an object that consists of two keys: name and value. name is the name of the color and value is the hexadecimal value of the color as a string. The "#" for the hexadecimal value is optional.
"colors": [
{"name": "Red", "value": "#FF0000"},
{"name": "Green", "value": "#00FF00"},
{"name": "Blue", "value": "#0000FF"}
]
Cpick comes with three color types as a default: CSS, Solarized, and XTERM. In order to fix complicated import problems, the JSON data is present in the colors.go file as a string. The preset data always has the lowest priority for being used.
Cpick has a testing mode that can only be enabled by calling Start with testing mode enabled. This automatically happens when you run go test in the cpick directory.
All of the tests can be found in the tests.go file.
