Apparently blue in plants and foods is a warning sign that it could be poisonous and so we naturally shy away from foods that look blue. Apart from blueberries that is. So in a moment of madness I decided to get some blue food colouring and dye a few bits of food to see what it looked like. Even if it was safe to eat I wouldn’t want to eat any of this stuff.
Blue milk on your cornflakes? I think not.
What’s that black monolith doing in my garden?
