Stephanie Vozza summarized research that looks at how the colours of the walls of an office affect performance:

• Red increases the heart rate and raises blood pressure. It is a good wall colour for employees who have to focus on details.
• Blue settles the nerves and is good for those working on creative tasks, or looking to brainstorm.
• Green is similar to blue in that it’s good for innovation.
• Yellow creates optimism but too much seems to create anxiety. People are more likely to yell at each other in a yellow room.
• In contrast walls painted white – the preferred colour of offices around the world – seem to lead to an increase in errors.
• Personality matters. “High-Screener” individuals aren’t as affected by the colour of walls as “Low-Screener” ones.

Read about the studies, the methodologies, why grey isn’t that great a colour either, and more over here.
