In a conversation with Daniel Birnbaum, Håkan Rehnberg said this about his art:

"I move the colour around, as if ploughing through a somewhat unknown terrain, with a wandering and unpredictable gesture. Fundamental is how layers are visually and physically overturned. I stop at the moment when the painting has reached an ultimate expression of precision, often in a mix of euphoria and resignation. In some of the paintings, I test my work against Carl Fredrik Hill and his late paintings of beaches, where seaweed and sludge glimmer in the shallow tide. It is like a surface that emerges and recedes, everything lies beneath and above a shimmering water surface, twisting in the tide, both beautiful and repulsive at the same time. But it is not the visual connection I seek, but rather the idea of a ground and boundary in dissolution."
