Remember, the XParseColor() system remains in wide use by other
x11 apps. If emacs used "#RRGGBB" in an incompatible manner, we'd then
be getting bugs about the colors not matching anymore between emacs
and other apps on x11 when people use the "same" values, e.g.
launching both
xterm -fg '#fedcba' -bg '#123456'
emacs -fg '#fedcba' -bg '#123456'
one would expect them to look the same.
I think keeping emacs unsurprising to x11 folk is good, given x11's use
as the main free gui...
Another option in the design space could be to have an "emacs:" super-
prefix that does colors in a standard emacs space* e.g.
"emacs:#334455". Emacs could also bundle its named-colors table (it
already does for non-x11 use) declared in the space, so you could do
"emacs:Tomato", while anything not prefixed that way is passed through
to XParseColor(). Then e.g. "emacs:#RRGGBB" would be potentially
different to an "#RRGGBB", "emacs:Tomato" potentially different to
"Tomato".
Or you could flip that, and have an "x11:" super-prefix that means
"pass the remainder through to XParseColor()", while unprefixed is
handled in the emacs space, but people will, as above, expect command
line args and X resources on x11 to be interpreted in the x11 manner,
so such a prefix might then have to be implicitly added for those cases.
Either way, that's a bit different to just having srgb: - it handles
named colors in a cross-platform manner, and leaves it possible for
emacs to support more syntaxes internally - Hey, I suppose supporting
the CSS3-color syntax [1] in general would be neat, either prefixed or
unprefixed. Have to remember that the x11 (and therefore historic
emacs) color names and html/css color names clash somewhat, sigh [2]
...Or we could stop using string specs and have an actual color type,
maybe with strings in color slots interpreted backward compatibly...
* presumably srgb in practice, while it's sometimes criticised, it's a
reasonable choice, it is a text editor we're talking about.
