Testing website contrast on Mac OS X

Posted on March 31, 2006

Having checked out GrayBit, it occured to me that those of us who develop/design on OS X already have a set of tools at our disposal for testing the effectiveness of the contrast in our designs.

In the Universal Access pane in System Preferences, you can switch your display to greyscale. Adjust the contrast slider towards the center and a lot of low-contrast details disappear. Go all the way to maximum and most of the OS X interface becomes indistinguishable, particularly in greyscale mode.

It's obviously a pretty rough test, but it's better than nothing if you're concerned about developing a site for the elderly / visually-impaired.

That looks like a useful feature. I know we have plans to make a Graybit plug-in for Firefox at some point. That's the plan anyway.
