“What is true about heat and pain is also true about colour. The rock is no more red than it is hot or painful. It can only have a colour -- red, blue, yellow -- in the invisible life where the colour is felt, on the basis of 'feeling oneself' (se sentir soi-même). Life's feeling of itself and its feeling of colour is a pathos. Colour is not linked to a tonality through an external and contingent association that would vary with individuals. In the phenomenological substance of its flesh and being, colour is a sensation and subjectivity; it is this affective tonality and inner tone.”
