In a red light, the average price of products was rated lower 60% of the time, compared to the same set of products in a blue light. Also in a red light, people rated an unnamed drink as, on average, 16% cheaper, with 14% more people saying that they were likely to buy it than when in a blue light.
In both light colours, participants were much less likely to buy a range of products in a more intense red light 100% of the time. This suggests that light intensity is negatively correlated with positive consumer reactions:
The brighter the light, the more negative the shopping environment.
