Dear Skip Knox ,

Thank you for your comments on the 2006 Last Call Working Draft of the
Web Content Accessibility Guidelines 2.0 (WCAG 2.0
http://www.w3.org/TR/2006/WD-WCAG20-20060427/). We appreciate the
interest that you have taken in these guidelines.

We apologize for the delay in getting back to you. We received many
constructive comments, and sometimes addressing one issue would cause
us to revise wording covered by an earlier issue. We therefore waited
until all comments had been addressed before responding to commenters.

This message contains the comments you submitted and the resolutions
to your comments. Each comment includes a link to the archived copy of
your original comment on
http://lists.w3.org/Archives/Public/public-comments-wcag20/, and may
also include links to the relevant changes in the updated WCAG 2.0
Public Working Draft at http://www.w3.org/TR/2007/WD-WCAG20-20070517/.

PLEASE REVIEW the decisions  for the following comments and reply to
us by 7 June at public-comments-WCAG20@w3.org to say whether you are
satisfied with the decision taken. Note that this list is publicly
archived.

We also welcome your comments on the rest of the updated WCAG 2.0
Public Working Draft by 29 June 2007. We have revised the guidelines
and the accompanying documents substantially. A detailed summary of
issues, revisions, and rationales for changes is at
http://www.w3.org/WAI/GL/2007/05/change-summary.html . Please see
http://www.w3.org/WAI/ for more information about the current review.

Thank you,

Loretta Guarino Reid, WCAG WG Co-Chair

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?

----------------------------
Response from Working Group:
----------------------------

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.
