“We shall see hereafter, in considering ideas of beauty, that color, even as a source of pleasure, is feeble compared to form. But this we cannot insist upon at present,—we have only to do with simple truth; and the observations we have made are sufficient to prove that the artist who sacrifices or forgets a truth of form in the pursuit of a truth of color sacrifices what is definite to what is uncertain and what is essential to what is accidental.”[39]

“It is, indeed, by this that the works of Turner are peculiarly distinguished from those of all other colorists,—by the dazzling intensity, namely, of the light which he sheds through every hue, and which, far more than their brilliant color, is the real source of their overpowering effect upon the eye, an effect so reasonably made the subject of perpetual animadversion, as if the sun which they represent were a quiet, and subdued, and gentle, and manageable luminary, and never dazzled anybody, under any circumstances whatsoever. I am fond of standing by a bright Turner in the Academy, to listen to the unintentional compliments of the crowd,—‘What a glaring thing!’ ‘I declare I can’t look at it!’ ‘Don’t it hurt your eyes?’—expressed as if they were in the constant habit of looking the sun full in the face with the most perfect comfort and entire facility of vision. It is curious after hearing people malign some of Turner’s noble passages of light to pass to some really ungrammatical and false pictures of the old masters in which we have color given without light.”[40]

“What I am next about to say with respect to Turner’s color I should wish to be received with caution, as it admits of dispute. I think that the first approach to viciousness of color in any master is commonly indicated chiefly by a prevalence of purple and an absence of yellow. I think nature mixes yellow with almost every one of her hues, never, or very rarely, using red without it, but frequently using yellow with scarcely any red; and I believe it will be in consequence found that her favorite opposition, that which generally characterizes and gives tone to her color, is yellow and black, passing, as it retires, into white and blue. It is beyond dispute that the great fundamental opposition of Rubens is yellow and black, and that on this, concentrated in one part of the picture and modified in various grays throughout, chiefly depend the tones of all his finest works. And in Titian, though there is a far greater tendency to the purple than in Rubens, I believe no red is ever mixed with the pure blue, or glazed over it, which has not in it a modifying quantity of yellow. At all events, I am nearly certain that whatever rich and pure purples are introduced locally by the great colorists nothing is so destructive of all fine color as the slightest tendency to purple in general tone; and I am equally certain that Turner is distinguished from all the vicious colorists of the present day by the foundation of all his tones being black, yellow, and the intermediate grays, while the tendency of our common glare-seekers is invariably to pure, cold, impossible purples.”

“Powerful and captivating and faithful as his color is, it is the least important of all his excellences, because it is the least important feature of nature. He paints in color, but he thinks in light and shade; and, were it necessary, rather than lose one line of his forms or one ray of his sunshine, would, I apprehend, be content to paint in black and white to the end of his life.”[41]

For practical purposes truths of form are more essential than ‘truths’ of color; to mistake the size, shape, solidity, and texture of anything is far more disastrous than to mistake its color. The color-blind get on very well in the world, often without knowing their defect; but a person who was form-blind would not get on at all.

The correct appreciation of form is of such vital importance that two senses are brought to bear,—the sense of touch—the parent sense—as well as the sense of sight; and without the co-operation of the sense of touch, sight would be comparatively helpless in recognizing solidity, texture, contours, etc. In the appreciation of form touch gets on very well without sight, while sight could not get on at all without touch; but, happily, a sense so precious is never completely lost.

Ruskin constantly uses the phrases, “truths of form,” “truths of color,” and it is apparent that by these phrases he really means fidelity to natural effects. With him a drawing, be it of a stone, a leaf, a tree, a mountain, is not true unless it corresponds to the thing in nature; nor is a light or a shadow or a color true unless it corresponds to the effect in nature.

Now, so far as art is concerned, those so-called “truths” are of the least importance.

Suppose a musician were to talk of “truths of sound,” meaning thereby the more or less faithful imitation of the songs of birds, the rippling of waters, the roll of thunder. Every one would know that his art was of the most primitive character.
