plum-coloured

— When partially dry, describe with a hair pencil, between the patches, broad veins of a mixture of dark blue and Venetian red; with a feather, passing over these veins, a broader, irregular tracing of a fainter, more plum-coloured hue, which may be formed of the remnants of the last-named colours, thinned, and a little lake added, with some additional fine veins in this colour.
