Rousing Rime Lime

Old English rūsan, to rush — present-participle of rouse. As a color modifier, rousing implies a saturated-and-wakening-and-active quality, the bright color of dawn-chorus-and-morning-bell atmospheric-and-aural stimulation. Sits at the bright-and-active end of the grid, parallel to awakening and invigorating in usage.

Old English hrīm, hoar-frost-on-twigs.

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.
