Re: color contrast on 60pt logo letters

There is a nice Firefox extension available for Juicy Studio that checks for text size/color and up to WCAG 2.0 AAA


Download the extension to your desktop and then drag/drop onto Firefox and restart Firefox.

Hi Angela,

It's an interesting thought: since the current color contrast standard in WCAG has different targets based on a certain font size threshold, could a higher threshold be created with less stringent contrast requirements? The guideline says 18 points and higher, but it does seem like the requirement would be a little eased for 60 point text. I know there was some experimentation and math that went into deciding on the 18 points threshold, and the decision that it should be 4.5:1 below that font size and 3:1 above it. I guess the same process could be done for other font sizes. I don't recall seeing that anyone's done it, though.
