Thinking Scarves - The Creative Thinking System for Primary Schools

I would like to introduce a brand new concept in thinking. Thinking Scarves.

For a long time I was a huge fan of thinking hats... until a teacher one day wrote to me and said she did not like Thinking Hats as the Black Hat was very negative and could help to reinforce negative stereotypes about the colour black. In contrast, "White" was seen as a straight down the line, honest hat. The facts, pure and simple, without and falsification or misinterpretation.

I then thought I am a teacher. Why not simply reinvent the whole system - forget about hats - scarves are the answer. With scarves, you can share them between friends, creating a closer bond between the thinkers. Make a thinking system which works perfectly in a primary school environment.

Green - What is positive - makes you feel good?
Red - What is negative? What makes you feeling angry or upset?
Purple - what are your general feelings towards a character? Like purple, feelings can be hard to define.
Gold - Make 'n' Shake - Follow your dreams and all the streets will be paved in gold.
Blue : Facts - Facts, like the sea and sky can appear endless.
Guide: No scarves, just a handy bag to carry all the scarves in and organise them into some sort of order.

I would love other people's opinions on this concept.
