I just re-designed my Twitter avatar with a dash of fluorescent paint to stand out in the noise of social media. It is interesting how computer screens work. A really bright color is not yellow or orange, but rather the ones that sit on the edges between 2 colors. Mine is in between yellow and green. It is as if our eyes are being teased by interfering light waves that are just a bit off in terms of wave length.
Other examples of interfering colors are on the border of pink and blue, or green and blue. I blogged earlier about how great classical painters manage to create rich colors through a combination of color mixing, patterns, texture.
