I occasionally see articles from individuals working in marketing making claims about how colour affects consumer behaviour.
For example, the infographic below describes how to produce a 'landing page' for a website. It all sounds like reasonable advice for optimising websites, until I reach the bottom where it highlights how different colours can influence actions. This is a claim I've seen quite a few times and seems to seep into everyday conversation. I can understand how we might associate red with danger, blue with boys, pink with girls etc, but they aren't strictly the same thing (eg, behavioural). Are the claims rooted in science, or are they just a popular marketing trope?
