Colour Names 1

It's common knowledge that web colour names are derived from the X11 colour names. But the relationship is in reality a series of compromises. Here's a comparison list:

Notes:
  1. "Aqua" and "Cyan" are synonyms and refer to the same RGB colours.
  2. In X11 and hence web names, "Gray" (en-us) and "Grey" (en-gb) are synonyms.
  3. "Fuchsia" and "Magenta" are synonyms and refer to the same RGB colours.
  4. There is no equivalent of X11 "Gray/Grey" in the web colours. The closest is named "Web Gray/Gray" in X11 and maps to "gray/grey" in the web namespace.
  5. "Light Goldenrod" and "Light Goldenrod Yellow" are two distinct colours in both namespaces. Many online lists conflate the two.
  6. "Green" is different in the X11 (#00FF00) and Web (#008000) namespaces.
  7. "Maroon" is different in the X11 (#B03060) and Web (#800000) namespaces.
  8. "Navy/Navy Blue" can only be officially named "navy" in the Web namespace.
  9. "Purple" is different in the X11 (#A020F0) and Web (#800080) namespaces.
  10. "Rebecca Purple" was added to X11 and CSS 4.1.
If we exclude the three X11 colours ("Gray/Grey", "Maroon" and "Purple") that have no web equivalent, we are left with the 140 unique web colours.
