Flashing Ki-iro
Flashing Ki-iro (#B3D86C) is a true lime with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (81°, 58%, 64%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary indigo. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old English flasch, flash — present-participle of flash. As a color modifier, flashing implies a saturated-and-rapid-on-off quality, the bright color of emergency-vehicle and photographic-flash light-burst surfaces. Sits at the bright-and-flashing end of the grid, parallel to coruscating and flickering in usage.
The Japanese word for yellow — built from ki (yellow) and iro (color). Used in the warm palette of ukiyo-e woodblock prints, kintsugi-repaired ceramics, and the gold-leafed wallpaper of Heian-period palaces. The color refers to ki-iro-painted byōbu folding screens: a saturated, slightly cool pure yellow with the matte finish of mineral-pigment-on-paper. The Japanese cousin of yellow.
