5000 Pieces Colour Puzzles

​Clemens Habicht's  5000 COLOURS is a CMYK colour gamut jigsaw puzzle of 5000 pieces. Each tile is an individual colour and the task is to place each colour exactly in relation to every other colour. 
"This one is for all those who wrote and said that 1000 COLOURS wasn't a challenge. Multiplying the number of pieces by a magnitude of five makes the difference in hue between neighbouring tiles barely perceptible. "         
With adjacent tiles almost identical in colour this puzzle is designed with an original random ribbon pattern so that each piece is a distinctly different shape and can fit clearly in only one way.
