Koi Colour Studio is Norway’s first multi-disciplinary colour studio, and our goal is to contribute with the targeted and effective use of colour within urban spaces, architecture, interior architecture, product development and graphic design. We offer advice, courses, development and strategic guidance. Our small team all have varied backgrounds, but in each case with a special focus on colour.

Dagny Thurmann-Moe

Founding Partner and Creative Director

Dagny is one of the country’s foremost colour designers and has over ten years of experience in the field. In 2014, she started Koi Colour Studio (formerly Dagny Colour Studio), with the goal of being able to offer targeted colour consultation for both public and private clients.

Dagny is a driving force for increasing awareness about the targeted use of colour, and in 2017 she published the book Farger til folket! (Colour to the People!) with Cappelen Damm, a book about why and how we should use colour in a more targeted way in architecture, interiors, public spaces, fashion and car parks. The book is published in four countries. She is a well-known face in the media and often comments on colour use, trends and the value of the proper use of colour in architecture, interiors and fashion.
