Failure F13 relates to SC1.1.1 and not SC 1.4.1

To Working Group,	

Refer to
F13: Failure of Success Criterion 1.4.1 due to having a text alternative
that does not include information that is conveyed by color differences in
the image

Well this relates to the inadequacy of the text alternative and should be
flagged as a SC 1.1.1 failure. Not SC 1.4.1.
Re-writing the text alternative will fix the issue.
In this context, refer to example#2 for SC 1.4.1. This is an image with
appropriate alt text and the example explains that it complies with SC 1.1.1
too.
Any image with inadequate  / incorrect text descriptor is a SC 1.1.1
failure. Color in an image can be just one element  that conveys info.  
So I argue that  such images should not be flagged as SC 1.4.1 failures. 

Maybe this failure can be replaced with one that says: Using color as the
only method to convey state (active or selected ) of a tab.
