_Light-pink, and brown-pink._
These two colours ought rather not be used, as they both proceed
from the same vegetable principle, viz. the juice or extract got by
decoction from French berries by the help of acid salts; consequently
incapable to sympathise with or admit wax into their pores[12]; the
wax can take hold of them only superficially, which makes them appear
dry and gritty upon the picture, and will easily come off by rubbing
them with one’s finger. Those artists who cannot do without them,
will do well to grind them, the light-pink with a little light-oker,
and brown-pink with a little brown-oker, and they will keep a little
better; but red-orpiment and a little bone black, making as fine a pink
as that properly so called, it will be best to use the latter.
