"So they close together
Dressed in red and yellow
Innocent forever, sleeping children
In their blue soft rooms still dream"

Colours are fascinating. Ever since I had a fight with my best friend at 8 years of age over the colour of a t-shirt that we couldn't agree on despite the feverish discussion, I knew that people see colours a differently. Almost everyone has 3 cones in their retina which makes us see roughly the same colours, however, some superwomen have an extra cone, making them a tetrachomat able to perceive a wider range of shades than us ordinary folk. My obsession with how we perceive colours was further amplified by reading Jasper FForde's disturbing sci-fi novel Shades Of Gray, which presents a dystopia future in which people are set in a cast system based on the primary colour they perceive their world in.

In the world of fashion, colour is an expression of a feeling, an idea or a thought, however abstract. If it is sometimes hard to differentiate between prussian blue and navy blue or mauve and wisteria - in the emotional response or sight, it is never hard to tell apart red and yellow from blue , not to mention that the feelings they evoke in us are polar opposites to each other.

For my latest Coach post, I played with the exuberance of primary colours, the latest Turnlock Tie collection, some vibrant new threads and the breath taking Sydney harbour. All this vibrance is what street style photographers' hyperventilating dreams are made of ...
