Impressive and colorful images, @velimr! I think you put some of these images around here and I wondered how they kept so many umbrellas fastened. These days I was watching a report about a town in Portugal, which now I don't remember, which had an area where there were many umbrellas and was the delight of tourists. I think it must have been a cool experience for you to walk under them and see how the light varied according to the colors. A polychromatic vision, of rainbows! I embrace you
