Comment 1: Site listed in resources appears to have some issues

Original Comment:

The site listed as a resource in G17 and G18
(http://www.w3.org/TR/2007/WD-WCAG20-TECHS-20070517/Overview.html#G17)

juicystudio.com appears to return faulty values for colors entered.
The generated values does not match this document which is also listed
in the resources: http://trace.wisc.edu/contrast-ratio-examples/

Proposed Change:
juicystudio.com probably needs to doublecheck their application.

I have also made my own application for this, which you might consider
listing as a resource. This is available here:
http://www.colorsontheweb.com/colorcontrast.asp

The values generated with this matches the http://trace.wisc.edu
document for all values I have tested.

Thank you

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

We checked with Juicy Studio and they were indeed  using the
constant 0.3928 instead of 0.03928, which they've now updated in all the
color contrast tools from Juicy Studio. The results are now correct.

We have added your application to the Resources for G17 and G18  and
also to the resource list on the understanding 1.4.3 and 1.4.5 pages.

Thank you for bringing this to our attention.
