@ -101,6 +101,7 @@ The theme comes in two styles, `storm` and a darker variant `night`.
| tokyonight_sidebars | `{}` | Set a darker background on sidebar-like windows. For example: `["quickfix", "__vista__", "terminal"]` |
| tokyonight_dark_sidebar | `true` | Sidebar like windows like `NvimTree` get a darker background |
| tokyonight_dark_float | `true` | Float windows like the lsp diagnostics windows get a darker background. |
| tokyonight_cterm_colors | `false` | Enabling this, will use the `gui` colors to set `cterm` values to their nearest equivalent. Only needed when not using terminal colors |
