How different people interpret different colors and a visual map of their relations. The map itself is gorgeous. I'm tempted ask for another level of information on top of it though, such as the emotional connection to the various colors.
Recent projects have me looking into the senses more and more and how they relate to each other. Considering not only the visual aspect of an object, but also inputs such as sound and texture. For anyone who hasn't seen it already, the sound of color. I really like yellow and green. Now, what about the smell of color? Even tougher, the smell of sound?
