Sure, it only depends on the author's habits and likings. You can also use and
mix with "rgb(255, 255, 255)", "rgb(100%, 100%, 100%)" and "white". CSS3 will
even have more methods (HSL and RGB with alpha value).
> Some HEX colors don't seem to have an abbreviation.
What do you mean by "abbreviation"? There are only 16 color keywords in
CSS2*), 256 variations with three digit hex codes and 16.777 million with 6
digits or decimal rgb().
*) Yes, there are also the X11/SVG color names in CSS3: Color and already
recognized by most browsers for years, but I pretend they aren't there,
because they're highly illogic and unsystematic, thus unusable.
And can anyone tell me, why system color keywords should be written MixedCase,
while X11/SVG ones are given alllowercase and the one for the current color in
camelCase in the CR? Yes, I've reported that to the editors.

All color values in CSS2 correspond to the sRGB color space (as opposed to
e.g. CMYK), and thus are designations thereof. HSL is unambiguously
convertible to RGB.

Not every color space is correctly mappable to sRGB. AFAIK PMS (Pantone
Matching System), like RAL etc., is intended for physical world use, which are
only unreliably resembled on screens. Hint: subtractive vs. additive color

You want color profiles. The various notations are just that, notations.
