Configuration

colorInfo.fields

Ordered array of color fields to display.

colorInfo.excludedFields

Array of fields not to display. Overrides colorInfo.fields. If you only need to exclude one or two of the default fields, using colorInfo.excludedFields is the preferred approach.

colorInfo.languages

Defines which files and languages have color info enabled, and which color types are supported. The default language setting enables all css color values for css, sass, and less documents:

"colorInfo.languages": [
    {
        "selector": "css",
        "colors": "css"
    }, {
        "selector": "sass",
        "colors": "css"
    }, {
        "selector": "scss",
        "colors": "css"
    }, {
        "selector": "less",
        "colors": "css"
    }
]

Each element consists of:

• "selector" - VSCode document selector.

• "colors" - String or array of strings defining the types of colors to display information for. Valid values color types are:

  • css - All css color value types
  • hex - Css hex (#ff00ff or #f0f)
  • hex+alpha - Css hex plus alpha (#ff00ff77 or #f0f7)
  • rgb - Css rgb or rgba (rgb(1, 2, 3) or rgba(1, 2, 3, 0.5)) c
  • hsl - Css hsl or hsla (hsl(1, 2, 3) or hsla(1, 2, 3, 0.5))
  • css-colors-names - Css color names (red, blue)

VSCode does not currently support nested languages, so to enable Color Info in an html file, you must add:

{
    "selector": "html",
    "colors": "css"
}

To your colorInfo.languages setting. Make you add this setting to the end of the default colorInfo.languages setting so that you do not disable Color Info for the standard languages.
