Snips for the Color Blind

Today we released a new color blind mode on Summize: read all about it.

Color blindness (or color deficiency) affects about 10% of males (and <1% of women).  Take a look at how this Summize snip may appear to users with the most common variety of color deficiency, deuteranomaly ("green weakness"):

Yikes! As you can see, it is difficult to distinguish wretchedness from greatness from badness from swellness — only the yellow hue of so-so-ness differentiates itself.  The effect is particularly distressing when looking at buzz:

The noteworthy transition from green to red user sentiment is completely lost.

In color blind mode, snips are rendered from black-to-white rather than red-to-green.  Grayscale snips address all varieties of color blindness (even true color blindness of the rare monochromat).

This is the nutshell; please visit the color blind mode page on Summize to read a full account of our effort.

As you can imagine, after the initial launch of Summize we received "hate mail" from many visually distraught color blind users (one such user regarded our site a "torture chamber for the color blind").  To those users: we thank you for your advice and good humor; your feedback has gone directly into the new design.
