Colour is important. It determines our mood and our productivity. Science tells us that each colour is associated with a specific vibrational frequency. When there’s a predominance of one or two colours in our environment, that vibrational frequency – and the characteristics or qualities associated with that frequency – will tend to influence the activities conducted in that environment – and the attitude of those in it, and even around it. This issue is all about colour in both the traditional and non-conservative sense.
