Van Gogh and a strange coincidence

Von Gogh's bedroom

Reading Explorator last Sunday, I found a link to this news story about a digital reconstruction of Van Gogh's bedroom. Evidently, the walls were not painted blue but purple, but he used carmine lake (red) to add to the blue to get purple. The dye-based pigment had faded

The BBC news report was dated the very day that I started my two part series on my digital reconstruction of the Mona Lisa where the problems were not just the yellowing but the use of rose madder lake, another dye based red pigment.

Not synchronicity, just weird.
