The possible confusion may occur with reverse lookups. For example, if
one uses 'lightgrey' in code to create a Color object, it gets
passed around as numbers internally, and one is then writing out HTML,
one has to decide whether to use a 'reverse lookup' and find a name if
one matches, or to just output the RGB values. I can also see a
similar issue if anyone tried to build a GUI inspector with named
colors (sorry, 'colours' - sic) in dropdowns.
Anyway it's a theoretical future worry, not an actual one, so I''m
quite happy to have any common and useful colour names in there.
