Kamakura Village by Katsushika Hokusai

Safflower 紅花(benibana): An organic red colorant obtained from the florets of Carthamus tinctorius, it produces a wide range of colors from red to pink. The florets are picked, then dried and crushed into a paste. The paste is washed with water to remove the non-lightfast yellow chromophors including several quinochalcones. The red colorant, primarily carthamin, is then extracted in an alkaline bath. The deepest reds are obtained through several initial washings to remove all of the water-soluble yellows. Safflower was grown throughout Edo Japan for use as cosmetics as well as food dyes. The area of Yamagata was known as a producer of high quality benibana and still produces it today.

Safflower is also the most commonly used red with dayflower to produce purple. This combination of safflower and dayflower is continually detected even after the introduction of synthetic colorants such as Prussian blue and aniline dyes, which seems to indicate that the tone obtained by the two was preferred over other possible mixtures of reds and blues.

Analysis

Excitation Emission Matrix (EEM) spectroscopy can easily identify the organic reds: safflower, madder, and sappanwood. Safflower fluoresces brightly under UVA radiation and produces a unique EEM pattern, even when the safflower has visually faded to a dull brownish red. In addition to the fluorescence for the red chromophor, the pattern often contained an additional peak for the yellow chromophore that was supposedly removed in the preparation of the red colorant but often needed several washings for complete elimination.
