Electric End Goldenrod

From the Greek elektron, amber — the substance whose static-electric properties were observed by Thales of Miletus. Used as a color modifier since the late nineteenth century after electric light made certain saturated colors feel attention-demanding. Electric blue, electric pink: the implication is hot luminance combined with optical impact. Sits at the bright-bucket extreme.

Old English ende, end / finish. As a color modifier, end implies a final-and-conclusion quality, the visual register of day's-end-and-year's-end final-and-conclusion close-of-period-and-end-of-day twilight-and-final-light surfaces under twilight close-of-period light. Sits at the modifier-and-time end of the grid, parallel to fall and eve in usage.

Solidago, the late-summer wildflower of North American meadows whose tall sprays of small yellow flowers signal the end of the growing season. The color refers to the flower head at full bloom: a warm, slightly muted yellow-orange with the matte finish of small clustered florets. Cooler than mustard, deeper than dandelion. The state flower of Kentucky and Nebraska, a pollinator magnet, and the original native dye for early American homespun.
