Red Colorants in Ukiyo-e Prints

 

Many pigments and dyestuffs (the latter are water-soluble) used in ukiyo-e prints are susceptible to fading when exposed to visible wavelengths of light, and a few fragile colorants also change their appearance when exposed to air, ozone, or moisture. Eighteenth-century colorants used in ukiyo-e are especially fugitive and most surviving examples are found in various states of fading.

Inorganic colorants tend to be relatively stable, although lead-based pigments will darken or tarnish chemically due to combining with atmospheric sulfides, and vermilion (mercury sulfide) will darken physically. Organic colorants, however, such as reds and yellows lose their intensity while the blues and purples (the latter usually a mixture of blue and red) fade into grays, tans, or buffs. Blue colorants made from the dayflower (aigami) and indigo (ai) have poor lightfastness, while safflower red (beni) fades at nearly the same rate.

Several studies on colorants in Japanese prints indicate that it was fairly common to find three types of yellows, two reds, and two blues in a single print. In Japanese printmaking of the eighteenth and nineteenth centuries, three types of organic red were used:

Plant Source Japanese Name Common English Names Color
Caesalpinia sappan suo, suhô (蘇芳) Sappanwood red
Carthamus tinctorius benibana (紅花) Safflower red
Rubia akane akane (茜) Japanese madder red

There were also three types of inorganic red colorants found in Japanese woodblock prints; the last, vermilion (mercury sulfide), seems to have been rather uncommon in prints, though not so in paintings):

Mineral Source Japanese Name Common English Names Chemical Formula Color
Hematite benigara (紅殻) Red ocher Fe2O3 red
Red lead tan (丹), entan (鉛丹) Red lead Pb3O4 red
Vermilion shu (朱), shinsha (辰砂) Vermilion HgS red

To help verify the use of more than one red in a single ukiyo-e design without recourse to scientific instrumentation and methodology (for such research, see references below), we can examine the changes, if any, in the appearance of the colorants over time. On this page (see images above), four impressions of a print by Shunbaisai Hokuei published in 8/1835 are shown. Portrayed are (R) Arashi Rikan II (嵐璃寛) as Hirai Gonpachi (平井ごん八), and (L) Nakamura Tomijûrô II (中村富十郎) as Komurasaki (小むらさき) [小紫] in the play Hiyokumon sato no nishiki-e (Brocade picture of lovers' crests in the pleasure quarters: 双紋郭錦絵) at the Naka Theater, Osaka.

The four impressions reveal different stages of fading for one of the red colorants, while a second red colorant (used on the sleeve and inner robe of Arashi Rikan II) remains virtually unfaded across the four specimens (apparent changes in precise hue of the second red colorant in these illustrated examples are due to photographic artifact). Presumably, the red prone to fading is benibana, as it has been established scientifically as a very fugitive colorant. (The far more colorfast red has not been identified for these particular specimens.) Although the sheets were imaged under different lighting conditions and with different cameras or devices, the fading of the benibana is dramatic enough to provide a useful idea of the eventual changes in appearance caused by prolonged exposure to light.
