Water-blue panels in dynamic fan shapes once filled the arches

Looking carefully through my files, I found a photo of Museum London clad with the original deep-blue metal panels.

If you look carefully, you might notice the dynamic fan shapes filling the arches. These disappeared at the same time that the colour was changed.

It is too bad that the colour reproduction in the two images is so different. Different cameras, different chips and taken at different times. Ah, the weakness of photography. It has been ever thus. Film was just as bad. When I was studying photography I had to write a paper comparing skin tones when using Kodak film, Fuji film and Agfa film. Totally different looks.
