Grayscale on safari

The entire option to switch to grayscale is something that really isn’t useful to users; it’s only useful to developers when trying to get a good overview of whether your color contrasts are sufficient on the page. I generally suggest leaving it disabled except when you’re doing testing and reviewing your site.

I am also experiencing that the greyscale icon doesn’t work in IE and Windows Safari.

It’s disappointing to me that there is an icon that isn’t supported across all major browsers. Hope you will reconsider supporting this … as it makes the WP Accessibility appear to be “broken” … for folks that use those browsers!
