accessibility testing of web pages

[patty]

I've been using HTML_CodeSniffer to do accessibility testing of web pages.  I have been successful reducing errors to 0 but I get lots of warnings about color ratio, text on background images.  My page is primarily white background with black or blue (links) text.  Is there something I can do to get rid of the warning?  If you are familiar with accessibility test, do warnings count against you?  Basically, I'm ignoring warnings.

It just pointing out with background image and colour, that you should have contrasting text, it not warning you about a actual problem with page not conforming to accessibility standards, well not with those ones listed. I don't know if there is an option to skip, as you have followed the rules suggested?
