For me, each nuance of a color is in some way an individual, a being who is from the same race as the base color, but who definitely possesses a distinct character and personal soul.
Yves KleinBlue suggests the sea and sky, and they, after all, are in actual, visible nature what is most abstract.
Yves KleinI had left the visible, physical blue at the door, outside, in the street. The real blue was inside, the blue of the profundity of space, the blue of my kingdom, of our kingdom!.. ..the immaterialisation of blue, the coloured space that can not be seen but which we impregnate ourselves with.
Yves KleinThe essential of painting is that 'something', that 'ethereal glue,' that 'intermediary product' which the artist exudes with all his creative being and which he has the power to place, to encrust, to impregnate into the pictorial matter of the painting.
