4 Basic Kinds of Lines & Colour
Originally published in 1977, the publication stands as an enduring example of LeWitt’s rigorous process-driven practice which utilizes simple conceptual parameters to generate complex and formally-diverse visual works.
Four Basic Kinds of Lines & Colour is a composite of two earlier publications—Four Basic Kinds of Straight Lines (1969) and Four Basic Colours and Their Combinations (1971). Each left-hand page offers a black and white study of four types of lines (vertical, horizontal, right-facing diagonal, left-facing diagonal) executed in all possible combinations, while right-hand pages present a combinatory system of lines in four colors (yellow, black, red, blue). The book opens with a two-page ‘key’ overviewing all permutations that follow.
