Dolores Blog showed thousands of colors to people and asked them to name the colors they saw. They then plotted those names on a color Wheel, printed in the color. They have a blog post describing the project. The resulting image is beautiful. They then added a filter so you can search for different color names and see where it is on the wheel. It's based on a study to test the universality of language.
When I first saw this, I thought it looked like a type of tag cloud. I like how their filter let's you expand and contract the colors that appear on the wheel. It certainly helps to illustrate how ambiguous language is. I love that there are at least four different colors all called "chocolate."
It also started me thinking about what other types of visualizations could be done. There are certainly lots of things that could be done intersecting it with other data, depending upon what you are interested in. Being able to see the color names along with if the namer was colorblind, their gender, native language and other demographic data would be interesting. I found myself wanting to click on a color name to get more information like how many times that name was used for this color.
What ideas for visualizations do you have?
