Re: Any Illustrator Plugins for Checking Contrast?

Adobe Illustrator has support for testing color contrast built in, so unless it doesn't do what you need you won't need a plugin. In Illustrator's view menu, select "proof setup" and then choose the Protanopia or Deuteranopia filters to view the effect.

Thanks,

A quick check can be done by converting the graphic to gray scale to
desaturate the colors.

In Illustrator, Edit > Edit Colors > Convert to Gray scale.
In Photoshop, Image > Mode > Gray scale.

It's not a perfect test, but if there isn't enough contrast when the graphic
is in gray scale, there probably isn't enough when it's in color, either.

I was curious if anyone had ever seen any sort of illustrator or photoshop
plugin for visual designs to easily check contrast? I certainly saw Webaim's
very nice checker, but I was wondering if anyone had seen something
automatic/programmatic for visual designers that works in their native
design environment (such as illustrator).
