Venn Diagram of 7 color sets

This interactive visualization of 7 sets Venn Diagram was created by Santiago Ortiz. It is his own version of the 7-Way Venn which was referenced by Information is Beautiful and pinterest of David MacCandless and Orthocuban.

Inspired by the Newton's theories on lights and color spectrum,  Santiago Ortiz decided to use colors rather than numbers or letters to identify each basic set. He created an interactive and isomorphic version of the original 7 Venn Diagram, meaning that the same topology was kept and the surface areas were balanced, so each piece has a similar visual importance.
