If you blur the line between black and white you don’t get something new, original, or groundbreaking. You get grey. And everyone knows exactly what grey looks like, where it came from, and what it means. It’s not really blurring, it’s blending. Swirl all the colours in the rainbow, or try and create a new one that isn’t predisposed to the others. If you break the mould, you need to create the mould to start with – it’s nothing more provocative than clicking on the negative filter in photoshop.
