As you can see, it's blue. My wife got her father to paint it this colour when we bought it a few years ago.
It needed a repaint recently, so we got some more blue paint. Naturally, my father-in-law wanted to do it, however my wife was worried that painting the shed might be too much work for him. She therefore bought him an electric spray painter. He used it, and it worked. We now have a blue shed.
We also have blue grass:
and a blue shed floor:
and a lesser spotted lawnmower:
He did it in a fraction of the time it would have taken with a brush, although if you count how long it took him to clean the sprayer afterwards it worked out at about the same.
Oh well, it could have been worse. I could have had to do it...
