Perhaps I can throw some light on "purple".

Currently the colours in html.tmac are a mish-mash! .defcolor purple rgb #8e35ef .defcolor purple1 rgb #893bff .defcolor purple2 rgb #7f38ec .defcolor purple3 rgb #6c2dc7 .defcolor purple4 rgb #461b7e The colour "purple" matches neither HTML nor X11! In fact I ran my diff program comparing the official HTML colours against the colours in html.tmac (with surprising results) practically none of them matched! See attached HTML- TmacColours.pdf (this time "X=" colours are the colours in html.tmac). So then I wondered how the html.tmac colours compared with the X11 colours in ps.tmac. The results in X-TmacColours.pdf. First column "HTML=" value from html.tmac, "X=" X11 value from ps.tmac.
The idiots at Cadbury claim intellectual property rights over the colour generally referred to as "purple" and the words "colour purple". They are idiots because they cannot validly make such a claim -- perhaps in the UK, but only if the UK parliament has enacted a special law for that purpose.
If you doubt the veracity of the previous paragraph then I suggest you research the story behind "Coca Cola", and why Pepsi Cola dropped the word "Cola" from its brand. As a starting point, Coca Cola could not claim rights over the two words, nor any combination thereof, nor the font it commissioned, nor the formula for the beverage. So the company did not name the font (over which *name* it could make claims), held/holds the formula a closely guarded secret, and turned the misspelled words in the unnamed font into an integrated whole (which it can/did/does claim rights over) and, incidentally, turned the trademark into one of the most recognisable brands known to advertising.
Just because an explanation cannot be found on the Internet after a short time with Google does not mean that there is no explanation.
When proposing changes to long-standing *roff "idiosyncrasies" I suggest you consider the adage festina lente.
