Challenging our perceptions

I’ve always enjoyed optical illusions. And every now and then, it’s good to encounter a  new one.

The two spirals above are exactly the same colour – i.e. they are both  green (as shown on the right). It’s hard to believe it but there it is. The ‘blue’ appearance is simply our visual system calculating colour relative to immediately adjacent colours.

It’s healthy to be reminded every now and then that we happily interpret the world around us every day – scenes, events, conversations, motivations, emotions – but actually all these our interpretations are similarly affected (distorted even) by context.

Never be too certain…..
