If switch from base-16 to base-10, wouldn't 0-100 be a nicer range
than 0-1? But seriously...do we really want to be inventing a colour
format?

Do you think it's likely? I was actually thinking that 8 bit was
overkill, but then I'm thinking of a Flash editor. Maybe for beautiful
wall prints it does matter.

Ok, actually that leads to a more compelling argument: the #abcdef
format does sort of trap MapCSS within the website world, whereas it
has every right to be used for print maps that have never seen a
browser. (But then, allowing both #abcdef and rgb(35.672,99.99,0)
achieves that...)
