Safflower 紅花(benibana): An organic red obtained from the florets of Carthamus tinctorius, it produces a range of tone from pink to red. The florets are picked, washed, massaged, and fermented to create safflower cakes (紅餅 beni mochi). The safflower cakes allows for the red dye to be easily preserved. Dried florets can also be used and are 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. Safflower was grown throughout Japan during the Edo period 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 can be a light pink, such as the delicate pink used to depict the subtle eye shadow or blush to a deeper red. Safflower was noted to be expensive and require multiple printing to achieve a darker color. Safflower and madder are the most commonly found red until the introduction of aniline dyes. Red safflower and madder are found as a single colorant or as a mixture of the two. Although a visual difference between a single colorant red safflower and red safflower/madder mixture is hard to discern currently, madder may have been mixed to extend the safflower. Safflower is also most commonly used 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 under UVA radiation and produces a unique EEM plot, 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.
