Checking this it's not quite black and white stripes, but there is no red, the strawberry illusion on the same source page is equally, if not more so, jarring and I assume someone with no knowledge of strawberries or a Coke can would be more likely to see things as they are because they have less knowledge of what they should look like. TBF I was watching an OK, in the sense it was very competent, film and checked afterwards. It had a better ending than I remembered.
