# Changing kitty colors

The themes kitten allows you to easily change color themes, from a collection of over two hundred pre-built themes available at kitty-themes. To use it, simply run:

    kitty +kitten themes

The kitten allows you to pick a theme, with live previews of the colors. You can choose between light and dark themes and search by theme name by just typing a few characters from the name.

The kitten maintains a list of recently used themes to allow quick switching.

If you want to restore the colors to default, you can do so by choosing the `Default` theme.

New in version 0.23.0: The themes kitten

## How it works

A theme in kitty is just a `.conf` file containing kitty settings. When you select a theme, the kitten simply copies the `.conf` file to `~/.config/kitty/current-theme.conf` and adds an include for `current-theme.conf` to `kitty.conf`. It also comments out any existing color settings in `kitty.conf` so they do not interfere.

Once that’s done, the kitten sends kitty a signal to make it reload its config.

## Using your own themes

You can also create your own themes as `.conf` files. Put them in the `themes` sub-directory of the kitty config directory, usually, `~/.config/kitty/themes`. The kitten will automatically add them to the list of themes. You can use this to modify the builtin themes, by giving the conf file the name `Some theme name.conf` to override the builtin theme of that name. Note that after doing so you have to run the kitten and choose that theme once for your changes to be applied.

## Contributing new themes

If you wish to contribute a new theme to the kitty theme repository, start by going to the kitty-themes repository. Fork it, and use the file `template.conf` as a template when creating your theme. Once you are satisfied with how it looks, submit a pull request to have your theme merged into the kitty-themes repository, which will make it available in this kitten automatically.

## Changing the theme non-interactively

You can specify the theme name as an argument when invoking the kitten to have it change to that theme instantly. For example:

    kitty +kitten themes --reload-in=all Dimmed Monokai

Will change the theme to `Dimmed Monokai` in all running kitty instances. See below for more details on non-interactive operation.

## Source code for themes

The source code for this kitten is available on GitHub.

## Command Line Interface

    kitty +kitten themes [options] [theme name to switch to]

Change the kitty theme. If no theme name is supplied, run interactively, otherwise change the current theme to the specified theme name.

### Options

--cache-age <CACHE_AGE>

  Check for new themes only after the specified number of days. A value of zero will always check for new themes. A negative value will never check for new themes, instead raising an error if a local copy of the themes is not available. Default: `1`

--reload-in <RELOAD_IN>

  By default, this kitten will signal only the parent kitty instance it is running in to reload its config, after making changes. Use this option to instead either not reload the config at all or in all running kitty instances. Default: `parent` Choices: `all`, `none`, `parent`

--dump-theme

  When running non-interactively, dump the specified theme to STDOUT instead of changing kitty.conf. Default: `false`

--config-file-name <CONFIG_FILE_NAME>

  The name or path to the config file to edit. Relative paths are interpreted with respect to the kitty config directory. By default the kitty config file, kitty.conf is edited. Default: `kitty.conf`
