Çò que permet de pénher es la percepcion e representacion de l'intensitat. Cada punt dins l'espaci a una intensitat desparièra, que se pòt representar en pénher per negre e blanc e totas las nuanças de gris entre. In practice, painters can articulate shapes by juxtaposing surfaces of different intensity; by using just color (of the same intensity) one can only represent symbolic shapes. Thus, the basic means of painting are distinct from ideological means, such as figuras [[Geometria|geometricas]], various points of view and organization (perspective) and symbols. For example, a painter perceives that a particular white wall has different intensity at each point, due to shades and reflections from nearby objects, but ideally, a white wall is still a white wall in pitch darkness. In technical drawing, thickness of line is also ideal, demarcating ideal outlines of an object within a perceptual frame different from the one used by painters.
