Let's be clear that rgba color *format* is already in the CSS 3 Color 
Module CR draft.  The current draft includes rgba (xxx, xxx, xxx, 
<alpha>) and rgba (xxx%,xxx%, xxx%, <alpha>) as the only two 
available notational forms to express that color format.  My 
suggestion is to add a hex notation form to those already proposed. 
E.g. color: #xxx<alpha> and color: #xxxxxx<alpha> - either with or 
without a delimiter before the <alpha> portion.  The reason for the 
suggestion is to preserve the most common color notation format 
presently in use in CSS when used for alpha colors.  In my view, it 
is worth the effort to make the use of the property as easy for 
current and future authors as possible.
