< p > First you'll need to place selected themes in your < code > themes< / code > directory (i.e < code > ~/.config/helix/themes< / code > ), the directory might have to be created beforehand.< / p >
< p > To use a custom theme add < code > theme = < name> < / code > to your < a href = "./configuration.html" > < code > config.toml< / code > < / a > or override it during runtime using < code > :theme < name> < / code > .< / p >
< p > The default theme.toml can be found < a href = "https://github.com/helix-editor/helix/blob/master/theme.toml" > here< / a > , and user submitted themes < a href = "https://github.com/helix-editor/helix/blob/master/runtime/themes" > here< / a > . < / p >
< h2 id = "creating-a-theme" > < a class = "header" href = "#creating-a-theme" > Creating a theme< / a > < / h2 >
< p > First create a file with the name of your theme as file name (i.e < code > mytheme.toml< / code > ) and place it in your < code > themes< / code > directory (i.e < code > ~/.config/helix/themes< / code > ).< / p >
< p > Each line in the theme file is specified as below:< / p >

< / code > < / pre >

< p > It's recommended define a palette of named colors, and refer to them from the
configuration values in your theme. To do this, add a table called
< code > palette< / code > to your theme file:< / p >

ui.text = " black"
[palette]
white = " #ffffff"
black = " #000000"
< / code > < / pre >
< p > Remember that the < code > [palette]< / code > table includes all keys after its header,
so you should define the palette after normal theme options.< / p >
< p > The default palette uses the terminal's default 16 colors, and the colors names
are listed below. The < code > [palette]< / code > section in the config file takes precedence
over it and is merged into the default palette.< / p >
