I am quite sure that any person familiar with natural objects will never be surprised at any appearance of care or finish in them. That is the condition of the universe. But there is cause both for surprise and inquiry whenever we see anything like carelessness or incompletion: that is not a common condition; it must be one appointed for some singular purpose. I believe that such surprise will be forcibly felt by any one who, after studying carefully the lines of some variegated organic form, will set himself to copy with similar diligence those of its colors. The boundaries of the forms he will assuredly, whatever the object, have found drawn with a delicacy and precision which no human hand can follow. Those of its colors he will find in many cases, though governed always by a certain rude symmetry, yet irregular, blotched, imperfect, liable to all kinds of accidents and awkwardnesses. Look at the tracery of the lines on a camp shell, and see how oddly and awkwardly its tents are pitched. It is not indeed always so: there is occasionally, as in the eye of the peacock's plume, an apparent precision, but still a precision far inferior to that of the drawing of the filaments which bear that lovely stain; and in the plurality of cases a degree of looseness and variation, and, still more singularly, of harshness and violence in arrangement, is admitted in color which would be monstrous in form. Observe the difference in the precision of a fish's scales and of the spots on them. XXXVIII. Now, why it should be that color is best seen under these circumstances I will not here endeavor to determine; nor whether the lesson we are to learn from it be that it is God's will that all manner of delights should never be combined in one thing. But the fact is certain, that color is always by Him arranged in these simple or rude forms, and as certain that, therefore, it must be best seen in them, and that we shall never mend by refining its arrangements. Experience teaches us the same thing. Infinite nonsense has been written about the union of perfect color with perfect form. They never will, never can be united. Color, to be perfect, _must_ have a soft outline or a simple one: it cannot have a refined one; and you will never produce a good painted window with good figure-drawing in it. You will lose perfection of color as you give perfection of line. Try to put in order and form the colors of a piece of opal.
