ragbag is going to show you a colour you have never seen before: a greener green than you’ve ever seen not only can the human eye see x-rays, it can also see imaginary colours. i’m not talking about fictional colours (like douglas adams’ hooloovooo) but colours that no physical light source can produce. furthermore it is very easy to see these colours (without first having to wig out on peyote). the way it works is this » If a saturated green is viewed until the green receptors [of the eye] are fatigued and then a saturated red is viewed, a perception of red more intense than pure spectral red can be experienced. This is due to the fatigue of the green receptors and the resulting lack of their ability to desaturate the perceptual response to the output of the red receptors. i have made two image files to assist the prospective colour-adventurer on his or her quest to see—for the first time—an imaginary colour. open this image and this image in separate tabs. stare at the magenta pentagon for 30 seconds or so until it starts to grey. then quickly switch tabs to the green square. for the next 5 seconds, you should experience a greener green than you’ve ever seen. I’ve done it, and it is indeed pretty damn green.
