The pigments most frequently used were comparatively few, and different lots of the same pigment seem to have been far from uniform in hue. As to this and some other points upon which we should be glad to have light, no very certain information exists. We do not know how soon some of the colours began to fade. Internal evidence indicates that in some instances the change took place within a comparatively short time, as in the case of the lovely blue used by Harunobu and ShunshoÌ chiefly as a colour for sky and water. It appears to have been a compound tint formed of blue mixed with some other colour to modify its intensity. In the change which followed—possibly a chemical one—the blue disappeared in whole or in part, leaving in its stead a buff hue having peculiar depth and a soft, velvety texture. To our eyes the modified colour is often far more beautiful than the original, but the variation, it may safely be asserted, was not desired by the artist. The quality of the colour wrought by these changes explains why it is not possible to-day to reproduce the prints successfully. The printing process is still in use, and, as the plates in such publications as “Kokka” attest, very splendid results are still yielded by it. But some of the old pigments cannot now be obtained; and if they could be, we should still have to wait long years for time to mellow the prints made with them. Indigo can be had, but it is not the same indigo and its colour is not quite like the old, which was extracted from blue cloth imported from China. Beni can be made, but the secret of the blue added to it to produce the divine violet seen in many of the prints has been lost, as has that of the precious moss-green used by Utamaro. Many reproductions have been made during the last twenty-five years, and some of them are extremely clever; but the printing lacks depth, and when placed beside the old works they appear dull and lifeless. Colour-prints were made for many purposes. To some extent they were used as advertisements. Incidentally they served as fashion plates. Some were regularly published and sold in shops. Others were designed expressly upon orders from patrons, to whom the entire edition—sometimes a very small one—was delivered. The number struck from any block, or set of blocks, varied widely. Of the more popular prints many editions were printed, each one, as might be expected, inferior to those that preceded it. Not infrequently the Yedo publishers removed from their out-of-date blocks the marks showing their imprint, and sold them to publishers in Osaka and Nagoya, by whom poor and cheap editions were issued. Eiraku-ya of Nagoya, in particular, is said to have bought many old blocks, some of which were revamped in various ways before being reprinted. [HARUNOBU. The Sleeping Elder Sister.] HARUNOBU.
