The Collectors Edition.
Think in Colour by Hugo Puttaert (Visionandfactory) is a beautiful, bright book spanning the design studios creative output over the last 24 years. The book comes in the multiple cover formats that evolve from black to yellow, orange, red, purple, blue, green and back to black. The black area is printed using a ‘thermo’ print technique that disappears when exposed to heat – revealing all that beautiful colour.
