Dynamic Tart Lime

From the Greek dynamis, power — used as a color modifier since the late nineteenth century for hues that read as energetic and active. Dynamic red, dynamic orange: the implication is saturation combined with optical motion. Sits at the bright-bucket center alongside vibrant and lively.

Old English teart, sharp-or-acid-tasting. As a color modifier, tart implies a sharp-acid-and-fruit-puckered quality, the visual register of Bramley-apple-and-rhubarb-tart hand-sharp-acid-and-fruit-puckered Bramley-apple-and-rhubarb-tart-and-Yorkshire-orchard tart-and-sharp-acid-and-fruit-puckered surfaces under Bramley-apple-and-rhubarb-tart-and-Yorkshire-orchard Yorkshire-orchard-and-Kentish-Garden-of-England puckered-orchard-light. Sits at the modifier-and-flavor end of the grid, parallel to sour and tang in usage.

Citrus aurantiifolia and its key-lime cousin — small, intensely sour green citrus carried by Arab traders from Southeast Asia to the Mediterranean by the eleventh century, then to the Caribbean with Columbus. The color refers to the skin of a fully ripe Persian lime: a saturated, slightly yellow-shifted green with the matte finish of citrus rind. Cooler than chartreuse, sharper than sage, with the same chlorophyll the fruit loses if left to ripen to yellow.
