Outside in the evening... again!

This is the window of my laundry/utility room/downstairs loo. I think it used to be a scullery and pantry area in the past so I have no idea why it is so pretty. It is a nice feature to sit outside next to on the decking in the summer.
The wall is actually white, it just looks blue with the light from the coloured glass.
CAN ANYONE tell me why my pictures keep uploading SIDEWAYS?!
