I think we should be concerned about function before beauty. I'm not
against allowing a grey/black distinction, which should be unmistakable
with most rendering methods or printers, but anything more subtle than
that is simply not robust for the kind of world-wide and timeless
access to RFCs that we want.
To be specific, a drawing that attempts to use
http://www.htmlcsscolor.com/hex/333333 as distinct from black would
be useless IMHO. #666666 and #999999 will be hard to distinguish,
and #CCCCCC might be too faint with a fading ink cartridge. So I think
we should be rather conservative and, if we leave grey-scale in,
encourage people to use only a single medium grey, say #666666 .
I have no idea whether SVG allows such a restriction.
P.S. An upvote to the fine folks at http://www.htmlcsscolor.com/
What a nice site.
