Description
a11y details here: http://w3-03.ibm.com/able/devtest/webcontrast_aa.html http://www.w3.org/TR/UNDERSTANDING-WCAG20/visual-audio-contrast-contrast.html
The issue is the foreground colour defined in Button.css .tundra .dijitDisabled .dijitButtonText {
color: #7F7F7F;
}
If the colour is slightly darkened to #5D5D5D the contrast increases to 4.66 which passes.
Test case
Run contrast analyser http://www.paciellogroup.com/resources/contrast-analyser.html
Input these colours: foreground : #7F7F7F background : #E7E7E7(this is the colour of the disabled button image buttonDisabled.png, found in dojo16\dijit\themes\tundra\images)
The contrast is 3.24:1 which is below the 4.5:1 minimum.

Increase contrast on disabled Tundra button to comply with WCAG2.0 accessibility requirements. Please proxy commit for Michael Billau, CCLA on file with IBM.

Hello, sorry for the late response. I have confirmed that using #5D5D5D does increase the contrast and have submitted a patch.

In my opinion, the changed text color looks too much like the enabled text color after this change is applied. Also, I think only the claro theme has been instrumented to comply with accessibility guidelines.

Bill, do you think we should accept this change for Tundra, or close this ticket as wontfix based on the last comment from Doug Hays?

Let's just close it (for the reasons Doug said).
