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?; Related issues: (space separated ids); WG Notes: [EDITORZ] BBC: Late Comment, Gregg's response is below and issue is closed.; Resolution: The Hex already is RGB. So this formula works great for what you want to do. Just take the HEX number and break it into three pieces and use the three pieces directly (they are R, G and B) Or you can use one of the tools that do this automatically for you using the formula. Here is one tool. They have an updated one with the latest equations and it should appear at this address soon. http://www.wat-c.org/tools/CCA/LCRA/index.html; (Please make sure the resolution is adapted for public consumption)
