For the experiment I used a really old artwork of Emily and Herrington that I like. Emily is the one with red hair.
There is NO red in this image. If you zoom in on Emily's hair you will find it's actually a blue-gray.
I quite like this color filter as well. The reds are very vibrant. Enhancing the red improves the color illusion, which you can see below.
Colorecipe. The cyan/red color illusion is achieved by a 50% opacity overlay.
