: ON THE PRIMARY, RED.
Or Mineral Kermes. We have obtained this colour ranging from light
orange to deep carmine, of different degrees of brightness and
stability. Some of the tints stood well in a book, but faded on exposure
to light and air; and some even vanished when secluded from those
agents. It has more than once been recommended as a pigment, but our
experience is against its adoption by artists. The colour is not
affected by sulphuretted hydrogen.
