"Colour is the animator of my poetical ideal. It is the single most important device in my work, and the driving force behind its impact."

“It is through painting that I understand how to view architecture, appreciate the rhythm of a poem, draw pleasure from the structure of a well-composed sentence. And it is through painting that the complexity of music makes itself understood to me. It is through painting, in fact, that I am.”

“Art is reimbued with its genuine power and profundity in the architectural realm. Its real power lies in the cathedral, the shopping center, the hospital. Not in the studios of Soho and Chelsea or the galleries of Madison Avenue or Bond Street.”

“The self-inflicted isolation of the contemporary artist and the mistrust levelled against the architect are both important contributing factors in the current situation of architectural art. The painter is anxious to keep intact the historical image of artist as loner, the intense sensitive, the genius and “maestro”; while the architect, feeling the watchful eye of his client constantly over his shoulder, approaches any extra-to-budget expense, such as art, with considerable trepidation, guarding jealously any intrusion into his building by potential glory-thieves. – Clarke in the essay 'Towards a New Constructivism', from his 1979 book Architectural Stained Glass.”

“My art is an art for the working class.”
