The US movie La La Land grossed £4.37m in its second weekend and £14.91m in 11 days. The uplifting message in the movie extended from the music to the costumes particularly the yellow dress worn by Emma Stone. As a result, the fashion industry was quick to inform its consumers that wearing yellow would make them happy. However, when the Guardian asked me to comment on this, I explained that a factor influencing happiness (or mood in general) lies less not in the colour of our clothing; rather it lies what we believe about that colour (and clothing). Importantly, as expected, there are also many additoonal factors that influence our emotions. Read my interview with the Guardian, here.
