This picture was taken about one and a half year ago in Locarno, a village in the italian part of Switzerland. I think those frontages show some very nice colors. But see yourself if you can spot any differences.
No differences or all completely different? To me the original image and the protanope and deuteranope simulations look almost the same. The deuteranope one is maybe a little bit more pale. And the tritanope simulation looks almost like a greyscale picture to me.
