'And the lord spake, and said that there shall only be one colour for Total Reaction, and that colour shall be purple. And verily, when the purple whiteboard marker ran out and none could be found, there was a great wailing and rending of clothes, and none could learn to fly.
Until one came who would challenge the colour code, and did say unto them: ''Use whatever colour you like, as long as it can be understood."
At this, there was great rejoicing, and they were freed for ever more from the tyranny of those who would only use the traditional way of cat-skinning.'
