RE: contrast for images of text

Adam,
Color contrast is a AA issue, so it doesn’t matter if the text is in an image or is regular text, the contrast is a AA issue.

1.4.1 speaks to conveying information with color, such as “click on the green button” but you can still meet 1.4.1 with poor contrast because by not relying on color alone you’d need to include other information. For example, “click on the green button that says ‘go’!”.  It is possible to have text that is very low contrast on that button, and that is ok for 1.4.1, but would fail 1.4.3.

Subject: contrast for images of text

Would images containing text which don't have the proper contrast ratio fail at single A? I only see 1.4.3 (which is AA) mentioning the issue of contrast. I would have thought that images of text should fail at single A since the user agent has no way of overriding the css background and foreground color for these images?1.4.1 mentions the use of color to convey information and would seem a likely candidate to fail such an image, yet no mention is made there regarding images of text.
Thank you for any feedback
