Etymology

Plush
adjective

From the French peluche, long-haired fabric — borrowed into English in the seventeenth century for the deep-pile velvet imitation that became Victorian upholstery. As a color modifier, plush implies the optical depth that comes from a thick pile absorbing light: plush burgundy, plush emerald. Sits in the dark-and-saturated quadrant near velvet and deep.

Phlox
noun

The genus Phloxflame in Greek, for the brightness of its flower colors. P. subulata is the creeping moss phlox of rock gardens; P. paniculata is the tall summer-border phlox in cottage gardens. The color refers to a fresh blue-violet phlox cluster: a saturated, slightly violet-shifted blue-purple with the matte finish of densely packed five-petaled flowers. Cooler than wisteria, warmer than veronica.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
