By no means does minimalist mean a fear of colour.
Photographer Grant Hamilton (Iowa City, IA, USA) isn't afraid of it either, judging by his polaroids. Colour just bursts out of his photos.
This is especially true for his Geometries series, in which he zooms in on some very mundane objects, finding beautifully geometric shapes.
Hamilton scans his polaroids and blows them up to a larger prints, which he sells at his web shop. Worth a look!
