Something Luis Colon said to me sparked off a train of thought
Do the hats have a shape?
What shapes are they?
Do they have names?
What names do they have?
Whilst I'm not about to try and overturn dBT orthodoxy , I don't see adding shapes and names as detrimental to the colour aspect, so long as that aspect is retained, and rather like the idea of wearing my 'Curious Hat', whatever colour it might be
I know I would find shape easier to visualise than colour when dealing with the different aspects
Moreover, the colour-blind members of the Human Race, probably don't find 'Red' as emotionally engaging as the rest of us
So, what shape would my Green Hat be?
 Heaven forfend!
Then my 'curious' hat would, indeed, be curious :)
I'm not so sure that the fool represents Green though - After all, their role was one of critic ... satirist ... which would intimate, perhaps, hB rather than hG
Perhaps cliches should be appealed to nevertheless though, such as the fool's hat or the mortarboard of the teacher/professor, for instance, for different toles
What do other people think?
Something more modern! http://www.thesun.co.uk/sol/homepage/news/3404056/Thinking-cap-zaps...
One 'vote' for the White hat by Asa : )
When I was very little, a friend of my mother was involved with a Canadian guy
He explained to me ... although I've no idea whether he was pulling my leg or not  ... that Canadians could not pronounce the letter 'p' and would pronounce 'pool' as 'fool'
Well ... 'po' is half of 'pool' ... and, by that token, would be half a 'fool' in Canada at least - Which seems kinda appropriate, given the provocative nature of 'po' : )
 I at least find it difficult to believe that he was in a position to speak for the entire population of the country
