Re: Understanding SC 1.4.3 - application of contrast requirements to logos

HI Detlev,

Logos are not covered (they are an exception).   However, saying that our "corporate colors" are "Light blue on beige" so "all our pages are printed in those colors"  is not part of the exception.  That is a "corporate visual guideline" that "goes beyond a logo or logotype".  

PS - the way to ask an official question of the Working Group itself is via the public comments.  
This is an unofficial response from me as an individual explaining what the words in the guideline mean.   
Suggestions for changes in the understanding doc should go to the public comments list - which goes to the working group for handling.  (The WCAG itself is a standard so it is not editable.)
