Perception or Reality (continued)

by Gruff Davies

5. False dual colour spirals
This whirlpool is another striking example of our brains interpreting the same underlying physical reality to give us very different personal 'realities'. Look at the whirlpool. You see two colours of striped spirals, one green and one cyan, right? As far as the 'green' and 'blue' parts of this picture are concerned, the light your monitor is producing is exactly the same in both cases, yet you experience two very different subjective realities: green and blue! (Thanks to Professor Kitaoka again!)
