Luminosity ratios 1.4.1

Augh. RGB?  

Most of us use hexadecimal to set colors. That's what I've spent five
years teaching my user base. Now you give a method for determining
luminosity contrast ratios that assume we're setting colors with RGB.

Is there any chance you can also provide a method of calculation in
hex?
