Intraction of Color by Josef Albers
This book is available in a cheap paperback with relatively low-quality printing. The book still has some value through explaining the exercises but the colours are lacking quite a bit.
Yale University Press released a new, 300-page paperback version with screen printed colour plates. Interaction of Color : New Complete Edition sells for around €180.
‘Interaction of Color with its illuminating visual exercises and mind-bending optical illusions, remains an indispensable blueprint to the art of seeing. . . . An essential piece of visual literacy.’
— Maria Popova, Brain Pickings
