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.

His efforts devised a “rational way to describe color” through the of use clear decimal notation; using hue, value, and chroma into uniform yet independent dimensions within a three-dimensional space. This idea broke with the traditional approach of identifying colors through a naming scheme, which Munsell thought was “foolish” and “misleading”. Munsell Color System, Atlas of Color Charts. The color system Munsell built back in the 1900 ’ s continues to serve educators, visual artists, and the industries who depend on color matching technologies to produce their products and services. The Munsell Color Company website has a historical overview of Munsell’s legacy as well as examples of company projects that continue to advance the process of achieving accurate color.

Colors: What They Mean and How To Make Them

It would appear on first glance at this book’s title, that it is a “how-to” text for the hobbyist or textile artist on dye recipes. Some information is given on where pigments are derived from; how to use sources on where to find and create pigments for dying fabric. The real value of the book is not in the recipes but in the cultural history of the pigment sources and the meanings of color, all packaged in a beautifully designed book. Each thought-out chapter highlights a color and is illustrated with photos and fine art reproductions to reinforce the text. Not book for color theorists–but offers a good general survey of color and it's uses throughout the centuries. Written and (visually) presented to hold the reader's attention with interesting facts without overwhelming. Colors: What They Mean and How to Make Them by Anne Varichon
