Blue has no dimensions, it is beyond dimensions, whereas the other colours are not....All colours arouse specific associative ideas, psychologically material or tangible, while blue suggests at most the sea and sky, and they, after all, are in actual, visible nature what is most abstract.
Yves KleinI am against the line and all its consequences: contours, forms, composition. All paintings of whatever sort, figurative or abstract, seem to me like prison windows in which the lines, precisely are the bars.
