At University, I was involved in a volunteer project to redecorate one of the student areas on campus. We wanted to use vibrant colors and wanted to paint one wall purple. The school put its foot down: No Purple.
We managed to find a color called Scandinavian Blue that was, unambiguously, purple. We presented them with purple colored sample chip with Scandinavian blue written on it and they happily.
I like the idea of a paint company that sells many colors under the names of many other colors. A red could be deep sunset violet. A yellow could be sunshine red, a green could be forest orange.
