This is an excellent point. Opacity is generally specified in percentage
terms by design applications, and CSS uses values between 0 and 1 for the
opacity property. Conversion between these two units is trivial, and there's
very little room for confusion (only a tiny range of percentage values fall
between 0 and 1).

The fact that, as Patrick points out, there are "AA" values in #RRGGBBAA
which *look* like percentages is confusing in my book.
