What an amazing complex world it is. My interests, and therefore my blog posts, just scratch the surface.
And even if I take just one bit; say, colours, and how we perceive them, it doesn't seem to get any simpler!
Take the patterns above. Each contains only four colours and a dark background. Yet each interests me for a different reason. Some feel more serene and calming, and others definitely catch my eye more. Some individual colours predispose me to react, like red (blood). Of course Emergency signage and advertising makes use of these colours like red and orange that we find more alerting.
Then there's the placement of colours next to others. Highly contrasting colours like red and white or yellow and black, draw my eye. I once saw a white and black striped sea-snake while skindiving over a coral reef in Vanuatu, and although I had never seen one before it made me instinctively curl up my toes and swim away.
And of course the concentric bull's eye shapes draw me in to the centres. They are like a whole lot of predator eyes looking at me. The old OXO boxes are perfect examples of 'eyes' plus a good, bright red. It's hard not to look at circles, especially red ones, as you pass them on the supermarket shelf.
And then there's plain ol' personal preference. Everyone seems to have a favourite colour or two. Mine's green.
