Use colour=* to indicate the official colour associated with the object, for example the colour typically associated with a public transportation route. It is also often used to describe the real colour of an object like amenity=bench.

How to map

The value should be:

  • an RGB colour code (hex triplet), e.g. #FF0000 for red. This RGB code allows to describe about 16 millions distinct colors.
    A shorter RGB code with only 3 hex digits is also possible: it is equivalent to the 6-digit RGB codes where each individual digits (of the 3-digit code) are doubled (see examples in the table below). This short code (also standard in HTML and CSS) allows describing 4096 distinct colors.
  • a CSS colour name (mostly English colour name) in lower case (generic names should be preferred for non-specific colours, e.g. red instead of firebrick), and without any dash separator (when using composite colour names in the "extended color set" in the CSS specification).

The following 16 "basic" colour names (standardized in CSS for use in HTML and SVG) are recommended for best support in various map renderers.

Sample RGB hex Colour name   Sample RGB hex Colour name
  #000000 (or #000) black   #FFFFFF (or #FFF) white
  #808080 gray (or grey)   #C0C0C0 silver
  #800000 maroon   #FF0000 (or #F00) red
  #808000 olive   #FFFF00 (or #FF0) yellow
  #008000 green   #00FF00 (or #0F0) lime
  #008080 teal   #00FFFF (or #0FF) aqua
  #000080 navy   #0000FF (or #00F) blue
  #800080 purple   #FF00FF (or #F0F) fuchsia

A more extensive list of colour keywords has been specified by the CSS Color Module Level 3, which is supported by all major internet browsers. However, please keep in mind that these will not be recognized by all renderers. Hex triplets as described above are preferred in this case.

Deprecated tags

Note: There is also an alternate spelling color=* in lesser use, see a comparison in Taginfo. "Color" is the alternative used in the American English spelling, however the community usually prefers to use the British spelling for consistency. This alternative name is listed in Deprecated features.
