Pulsing Cycle Goldenrod

The progressive participle of pulse, to throb. Used as a color modifier for hues that read as if they were alternating between two states of luminance — the vibration of a high-saturation color against a contrasting background. Sits in the bright-bucket center alongside electric, with the implication of optical motion rather than static luminance.

Greek kýklos, circle / cycle. As a color modifier, cycle implies a repeating-and-circular-time quality, the visual register of seasonal-and-lunar-and-astronomical repeating-and-cyclic period-marker celestial-and-natural cycle-and-rhythm surfaces under repeating cyclic-and-seasonal light. Sits at the modifier-and-time end of the grid, parallel to phase and year 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.
