This is what the MA map on the front page of the @BostonGlobe looks like with Protonopia/Deuteranopia colorblindness! The green on dark gray also fails web content accessibility guidelines for color contrast. Color choices and contrast are important for accessibility #mapoli

Two thoughts:

It's likely these colors were chosen on higher end displays where colors are more distinct without regard for cheaper displays and how they show color. (Often a problem with macs vs PCs)

Counties should be light by default and dark when hovered for better contrast

While you're viewing this thread for some reason check out http://ballotdropma.com , a website I made to help MA voters find ballot drop boxes! It'll be useful in November again I suppose
