Did you know that colour can have a real psychological effect on people?

The city of Glasgow set up blue lighting in a selection of neighbourhoods and reported a decrease in crime rates, likewise, Japanese railway company Keihin Electric Express Railway Co. set up blue lighting on train station platforms to deter suicides. Although no scientific tests have been conducted, according to an article by John M. Grohol, Psy.D, there have not been any suicides reported since their installation.

As I just mentioned, some will disagree over what colours fuel what emotions, and there is a good reason for this. It is nearly impossible to objectively test the effects of individual colours because the effect they have is the result of a mixture of natural psychological responses and learned cultural meanings.

Charts like the one above give us a good starting point, but if you really want to know what works best, you will need to setup an A/B test. Try several colours and measure your conversion rate to see which colour results in the most sales.
