It’s been scientifically proven: blue and red artworks are the most attractive. At least to auction attendees buying abstract paintings in the US, China, and the Netherlands.
They found that blue paintings command 18.57% higher bids and stronger intention to purchase, while red paintings increase bids by 17.28%. In terms of average pricing, per standard-deviation increase in blue pigment (compared to a “benchmark white”), the works went up an average of $53,600. They went up $21,2000 for each standard deviation of red.
The researchers conducted lab experiments in China, the Netherlands, and the US to gauge participants’s “willingness-to-pay” and pleasure, finding the results “consistent across all three cultures.”
