Colour Haze is a stoner/psychedelic rock group from Munich, Germany fronted by Stefan Koglek.

Formed in the mid-nineties, Colour Haze is one of the oldest German stoner outfits, and have since then become one of the flagships of the German stoner rock scene. Since 1999 the lineup has been stable, with Stefan Koglek playing guitar and handling vocals, Manfred Merwald on drums and Philipp Rasthofer playing bass-guitar. Emerging from a sound heavily influenced by Black Sabbath on their first records, they shifted to a more improvised, jam-based sound, culminating in songs topping twenty minutes on the self-titled Colour Haze (2004).
