Is there a W3C or any other noteworthy standard on how to represent a color (including alpha channel) in hex format?
Is it #RGBA or #ARGB ?
+3
A:
I'm not sure if there is an official standard-
RGBA is the representation I've seen for Web Macromedia and others use ARGB
I believe that RGBA is the more common representation.
If it helps this is from W3 for CSS3

Also, the CSS function for specifying colors with alphas is rgba()

from the W3 link you posted: Unlike RGB values, there is no hexadecimal notation for an RGBA value.
