As I understand DeBono's '6 thinking hats' they are a tool to help clarify thinking process, each colour denotes an 'aspect' of thinking that can be applied to an issue, to summarise; * White represents a blank sheet of paper, this is about gathering and assessing 'raw'data & information in a non-judgemetal, non critical way. Getting the facts straight if you like... Or agreeing a goal/desired outcome * Red represents fire, this is about expression of emotional issues, eg,anger, fears, strong positive or negative feelings, etc * Green represents shoots or new leaves, this is about creativity, expression of creative solutions to problems, disregarding whether these are practical or not... * Yellow is sunshine, this is about consequence (positive)- taking an optimistic view
