I found this a really interesting read but I couldn't see evidence of the author's pyschological qualifications so I'm not sure how valid the conclusions were. Work for some large companies was discussed so their experience is impressive at least. That aside, I found it fun to read about people's different associations with colour. The questionnaire made me an 'Autumn' which coincided with a professional colour analysis I had done recently. It also happens to be my favourite season so maybe there is something in it!
