It may be that in some of my readers' minds--those who, like the sceptical friends I have mentioned, are not distinctly conscious of the cause or secret of the expression of a flower--some doubt may still remain after what has been said of the blue and purple-blue blossom. Such a doubt ought to disappear when the reds are considered, and when it is found that the expression peculiar to red flowers varies infinitely in degree, and is always greatest in those shades of the colour which come nearest to the most beautiful flesh-tints.
When I say "beautiful flesh-tints" I am thinking of the æsthetic pleasure which we receive from the expression, the associations, of the red flower. The expression which delights is in the soft and delicate shades; and in the texture which is sometimes like the beautiful soft skin; but the expression would exist still in the case of floral tints resembling the unpleasant reds, or the reds which disgust us, in the human face. And we most of us know that these distressing hues are to be seen in some flowers. I remember that I once went into a florist's shop, and seeing a great mass of hard purple-red cinerarias on a shelf I made some remark about them. "Yes, are they not beautiful?" said the woman in the shop. "No, I loathe the sight of them," I returned. "So do I!" she said very quickly, and then added that she called them beautiful because she had to sell them. She, too, had no doubt seen that same purple-red colour in the evil flower called "grog-blossom," and in the faces of many middle-aged lovers of the bottle, male and female, who would perish before their time, to the great relief of their kindred, and whose actions after they were gone would not smell sweet and blossom in the dust.
The reds we like best in flowers are the delicate roseate and pinky shades; they are more to us than the purest and most luminous tints. And here, as with bird notes which delight us on account of their resemblance to fresh, young, highly musical human voices, flowers please us best when they exhibit the loveliest human tints--the apple blossom and the bindweed, musk mallow and almond and wild rose, for example. After these we are most taken with the deeper but soft and not too luminous reds--the red which we admire in the red horse-chestnut blossom, and many other flowers, down to the minute pimpernel. Next come the intense rosy reds seen in the herb-robert and other wild geraniums, valerian, red campion and ragged robin; and this shade of red, intensified but still soft, is seen in the willow-herb and foxglove, and, still more intensified, in the bell- and small-leafed heath. Some if not all of these pleasing reds have purple in them, and there are very many distinctly purple flowers that appeal to us in the same way that red flowers do, receiving their expression from the same cause. There is some purple colour in most skins, and even some blue.
