Now that people can see blue, I have strong evidence in Google Trends that people can now see "Indigo." Soon we will all be seeing "Violet".... What is next...Ultraviolet?

Also, according to the on-line Etymyology dictionoary, the word Cyan is traced back to 1889. So by the reasoning in the video, prior that time, like 1850s, people viewed Cyanotypes as grey.

Sacre Bleu!​

that is made from lapis lazuli ( found in Afghanistan ) and its called sacred blue because it is used primarily in paintings of Mary. years ago I heard a report on NPR about it ( must have been 25 years ago ? ) and it talked about how it was one of the most precious commodities a painter could have and typically in the Middle Ages someone going to Afghanistan would have to haul out 4x as much as he needs because 3/4 was used to bribe bandits/highwaymen/robbers who would demand $ or product to let one pass...
