by Cathi Stevenson It has to be discussed…again. Visual vibration. So many independent publishers don’t seem to think it’s an issue and I’d bet my last chocolate-covered almond it’s resulting in lost sales. What is it? Visual vibration is caused when two bright colors are mixed together on a book cover or website or ad and they create an “afterimage” effect. It’s almost as if a dancing halo has been placed around the word or shape, making it nearly impossible to look at the image for any amount of time. It’s painful. It’s the last thing you want happening on your website or your book cover. You can avoid visual vibration by introducing a less vibrant, neutral color to the mix.
