< p > You can define a palette of named colors, and refer to them from the

< 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 >
