In despite of this, however, it is only through its employment of colour that the art of painting is able to give a real and vital presentment to the wealth of soul-life. All the schools of painting have, however, not retained the art of colouring at the same high level. It is a significant fact that we may, with an exception here and there, assert that it is only the Venetians and the Dutch[283] who have become consummate masters in their use of it. Both peoples were linked to the sea-coast, both situated on a low-lying land divided by fens, streams, and canals. In the case of the Dutch we may find an explanation in the fact that, on account of their having so perpetually a cloud-covered horizon, their conception of a gray background became fixed in their minds, and owing to this very gloomy prepossession they were the more driven to study colour in all its effects and variety of lighting, shadow, and chiaroscuro, to emphasize this and to discover in this the main task of their artistic efforts. In contrast to that of the Venetians and the Dutch the painting of the Italians generally, if we except that of Correggio and one or two others, appears to be more dry, sapless, cold, and lifeless. Looked at more closely we may emphasize the following points in connection with the art of colouring as the most important.
(_αα_) In the _first_ place we have the abstract basis of all colour in _light_ and _dark._ When we posit this contrast and its transitions by themselves without further distinctions of colour effect, we get thereby simply the contrasts supplied us by white as light and black as shadow together with their transitional grades and nuances, contrasts which offer to the art of drawing its integrating quality, appertaining as they do to the real plastic character of form, and producing the prominence, retreat, rondure, and distance of objects. We may incidentally mention in this connection the art of engraving on the plate which is wholly concerned with light and shadow as such[284]. Apart from the infinite assiduity and labour it implies we find in this highly valuable art, at the point of its supreme attainment, soul intimately associated with the utility of great variety of form[285], a variety which the art of bookbinding also possesses. Such an art, however, is not wholly occupied with effects of light and shade as that of simple draughtsmanship is; it endeavours further in its elaboration to become distinctly a rival of painting, and in addition to light and shade such as is purely the effect of illumination, also strives to express those distinctions of more emphatic light and darkness which are primarily the result of local colour; we find, for example, in a copperplate engraving that an attempt is made by its use of light effects to render visible the distinction between blond and black hair.
