Rising blue

This morning I read a post on Facebook by Mikhail Nisenbaum "Rublev blue" about the impossible blue color of Andrei Rublev. He did not give up, no matter how much they tried to reproduce it with modern colors: neither Prussian blue, nor azure, nor even ceruleum is able to convey the shade of living lapis lazuli in tempera. After reading, I went out into the street, and there - the first of March. And through the gloomy sky of the newborn spring, this most elusive dove shines. I came to the workshop with such a thirst for blue that I immediately rushed to paint an ascending angle - Prussian blue, azure, ceruleum - I even added indigo. And on the sides there is something angelic, and hton-hton-hton. Do not judge strictly - on the first day of March, everyone goes a little crazy
