Color Accessibility Tools for Web Designers

Selecting web colors for the general population and color vision deficiency users can present some challenges. In order to satisfy both audiences (as well as client needs), the web boasts some free tools to help designers make sound choices.

Using the accessibility standards set by the WC3 (World Wide Web ConsortiumContrast-A (a.k.a. Dasplankton) is a website that provides tools to build, preview, save and print custom color combinations all on-the-fly. With a highly functional and well designed interface, Contrast A offers a feature for producing hardcopy of your chosen swatches with a key indicating proper contrast for WC3 compliance. The site also displays text sampling of body copy and the ability to save custom palettes.


For launched websites, checkmycolors.com will do an audit on foreground/background colors as well as DOMs (Document Object Model). After the review, the website builds a laundry list of all hex colors with their corresponding HTML usage. Contrast ratios, brightness and color differences are rated with a check mark (for passing) or an “x” (for insufficient contrast). To double-check those colors that don't pass, just click once on the “x” mark and you will be presented with a breakout of the brightness, color difference and luminosity/contrast ratio. Whether you're hired to finish a website already started, or make improvements to an existing site, checkmycolours will do the job for making those last minute tweaks for WC3 compliance.

Another Pinboard to Follow

Having resisted Pinterest for about a year now, I finally dipped my toes into the virtual pool of pinboards. My apprehension was truly misdirected and I've come to find that the concept of organizing visual images/links onto a virtual board has become a great teaching tool. After covering the typical graphic design topics such as typography, and history it was a natural move to include color among the related topics. So here is a link to my All Color Matters pinboard .

Purple for the Privileged

Murex Brandaris For centuries, the color purple was both an elusive and exclusive hue. From the time of Ceasar till the conclusion of the Byzantine Empire, purple was worn by kings and those serving in a high office or positions of influence. Rulers like Nero would sentence anyone to death who dared to wear imperial purple. The Roman emperor Diocletain however, took a more economical approach by collecting taxes from anyone who was compelled to slip on the hue. Up until the 1850’s, the arduous process of acquiring this color was more involved then its close cousin—red. Not unlike red, purple was also derived from the animal kingdom. Farmed from the Mediterranean region by the Phonecians as far back as 1500 B.C., Tyrian Purple came from the mucous secretion of a predatory sea snail’s hypobranchial gland ( murex brandaris , murex trunculus , bolinus brandaris ). The sea snails were soaked and then boiled in large vats which allowed the “juice” to be removed from the gland. It t...

Color and Design

Not a book for light reading, Color and Design will satisfy any design practitioner, or scholar seeking to gain a more expanded view of how humans respond to color. Editors Marilyn DeLong and Barbara have curated a selection of essays which are organized into subjects ranging from color psychology  to marketing and trend influences. Since these are essays, the reader should not expect this book to offer a cultural analysis of primary/secondary colors nor an explanation of basic color theory. What the text does offer is specific examinations on various topics that center around sociological approach of how color is assimilated within a culture, its art, folklore and consumerism. Outwardly this can seem to be a real bore. I did however find a pearl or two that can potentially be assigned as required reading for my students. For example in Part III: Markets and Trends , I found an informative essay by Alex Bitterman ( Color the World: Identifying Color Trends in Contemporary Ci...
