According to this article, office color can make a big difference in how employees feel while at work.

Employees have revealed they get depressed when they work in an office that is painted blue.

Yellow offices made staff feel happy, energised and more focused on their work.

Employees said they felt angrier and more passionate if there was more red than any other colour, while black made them feel “tougher.”

The research by Konica Minolta also found that grey offices made workers feel “dull.”

Apparently it isn’t just a case of the Monday’s.
