REDDISH PURPLE (n.)
Whatever the general Character of the Story is, the Picture must discover it throughout, whether it be Joyous, Melancholy, Grave, Terrible, &c. The Nativity, Resurrection, and Ascension ought to have the General Colouring, the Ornaments, Background, and every thing in them Riant, and Joyous, and the contrary in a Crucifixion, Interment, or a Pietà. [The Blessed Virgin with the dead Christ]. [...] I have seen a fine Instance of a Colouring proper for Melancholy Subjects in a Pietà of Van-Dyck : That alone would make one not only Grave, but sad at first Sight ; And a Colour’d Drawing that I have of the Fall of Phaëton after Giulio Romano, shews how much This contributes to the Expression. ‘Tis different from any Colouring that ever I saw, and admirably adapted to the Subject, there is a Reddish Purple Tinct spread throughout, as if the World was all invelopp’d in Smould’ring Fire.
