Chromostereopsis effect is the result of an eye strain (asthenopia) caused by the optical fatigue after seeing two very contrasting colours in opposite spectrum. In this piece, MEK.txt utilised #FF0000 red and #0000FF blue. Asthenopia forces our eyes not be able to differentiate a clear boundary in the meeting point of the two colours, in this case, the dominant red colour appears to be larger, creating an illusion of separated depth where it seems to ‘move’ in front of the blue colour. This artwork also raises a question: Why the dithering technique used seems to be enhancing this effect, compared to using solid colour or smooth gradients? Chromostereopsis. Coming from eye strain (asthenopia), caused by the optical fatigue on seeing two very contrasting colours in opposite colour region (FF0000 red & 0000FF blue). • • • The simple formula to create Chromostereopsis effect: #FF0000 as the foreground, the main character, the focal point. #0000FF as the background, diluted in black by dithering or applying gradient (for a lesser effect) Make sure there's enough contact points of the red and blue.
