We don't need the rainbow song to tell us that colour has a potent effect on the mind.
Different hues conjure up diverse emotional responses within us.
Research shows that we associate brown with ruggedness, purple with sophistication and red with excitement, for example.
But it's also a matter of personal framing.
"How we perceive a colour depends on our experience, our expectations and the knowledge that we bring to it," Dr Carolyn Mair, Reader in Psychology at London College of Fashion (UAL), tells Grazia.
"The associations we have with colour – like yellow with a lovely sunny day and buttercups – can evoke an emotional and behavioural response."
And now a six-month global online poll of 30,000 people has revealed that this is officially our favourite colour:
The shade in question - an aqua green-blue teal - was selected by fine arts graduate Annie Marrs.
Participants from over 100 countries hovered over an infinite palette of shades until they chanced across a colour they found most attractive, in T_he World's Favourite Colour_ survey organised by Hull 2017 UK City of Culture and paper merchant GF Smith.
Results were then combined to find which colour was most popular overall; and the shade chosen by Annie was the closest match to this.
The winning hue has been named Marrs Green in her honour, and will get its own range of paper.
Annie says she was inspired by "really bright and vibrant and deep and rich shades" that "dance" on the River Tay in her home town of Dundee.
"I've always loved colours in the green / blue teal family," Annie tells the Telegraph.
“It feels absolutely amazing. It's an absolute privilege to have a colour named after me. It’s been a surreal experience but a very special one and quite overwhelming at times."
Annie's triumphant shade is now on show at a pop-up shop in Hull city centre, where all products featured come in her colour of choice (above).
A similar hue was chosen as Dulux's colour of the year in 2014.
Colour psychology expert Karen Haller says it's a shade that radiates serenity.
"Blue positively communicates feelings of tranquillity and calm, whilst green positively evokes feelings of peace and balance," she tells The Design Sheppard.
"Teal is a great colour to use where you wish to relax and unwind – to regain balance and equilibrium after a hectic busy day.
"This tone represents balance, calm, and soothing whilst also being restorative and rejuvenating – perfect for these unsettled, uncertain times."
