Hi,
Is there a minimum color contrast ratio for non-text content (icons, image
buttons without text etc) that a user can click to take some action?
Thanks!

WCAG only specifies contrast requirements for text and images of text.
Clearly users need adequate contrast for non-text interactive items
also. I think the WCAG level AA ratios (4.5:1 or 3:1 if it's a heavy
set graphic) provide a pretty good threshold for such things.
