Camille Walala deals in positive energy. And her mission is clear: to put a smile on the faces of typical bored and inexpressive urban dwellers. She is a purveyor of positivity expressed through vibrant colour and bold pattern. Her work, from the micro to the macro, harnesses optimistic typography and exuberant geometries to create environments that stimulate the senses and inspire joy. The work of this sought-after designer turned muralist have invaded the walls of London, Paris, and New York, and have caught the interest of brands like Facebook and Urban Outfitters and celebrities such as Katy Perry.
