It's basically the same picture as this one: https://pixelfed.de/i/web/post/760533026005110562 only this is the entrance to number 6, and it's blue :) 

Photo of building entrance number 6. Through semi-transparent wire glass, a staircase can be seen. The door is simple and kept in bright blue, with a black bar/handle across. A light blue mosaic extends to the left and right of the glass/door combination and to the borders of the picture. The staircase is painted yellow, this and the yellowish tungsten lighting give a nice contrast to the blue of the door/mosaic (blue and yellow are complementary colours). 

Again the left part of the mosaic has a few more columns than the right...
