bold_brightens_ansi_colors = true

When true (the default), PaletteIndex 0-7 are shifted to bright when the font intensity is bold.

This brightening effect doesn't occur when the text is set to the default foreground color!

This defaults to true for better compatibility with a wide range of mature software; for instance, a lot of software assumes that Black+Bold renders as a Dark Grey which is legible on a Black background, but if this option is set to false, it would render as Black on Black.

Since: Version 20230320-124340-559cb7b0

The functionality described in this section requires version 20230320-124340-559cb7b0 of wezterm, or a more recent version.

This option can now have one of three values:

  • "No" - the bold attribute will not influence palette selection
  • "BrightAndBold" - the bold attribute will select a bright version of palette indices 0-7 and preserve the bold attribute on the text, using both a bold font and a brighter color
  • "BrightOnly" - the bold attribute will select a bright version of palette indices 0-7 but the intensity will be treated as normal and a non-bold font will be used for the text.

You may use true or false for backwards compatibility. true is equivalent to "BrightAndBold" and false is equivalent to "No".
