The image shows a close-up of a blue glass window on the side of a building. The window is rectangular in shape and appears to be made of glass. The glass is reflecting the light from the window, creating a bright blue color. On the left side of the image, there is a gray concrete wall with a small black square in the center. The wall is slightly curved and has a textured surface. The image is taken from a low angle, looking up at the window.
