We should add to the article http://www.ldraw.org/article/218.html#colours that also the integer representation of the notation 0x2.... is allowed in ldraw files for <colour>.
Because we also have a hint for applications using this, we should give another hint what to display (which colour should be used) if the colour value that is found in a ldraw file is out of the specification.
