Imperial Tampopo

#7f991d
Notes

Imperial Tampopo (#7F991D) is a true yellow with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (73°, 68%, 36%) 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

Imperial
adjective

From the Latin imperialis, of the empire — applied to color since the medieval period for the hues reserved for sovereigns and empires: imperial purple of Tyrian dye, imperial yellow of Ming-dynasty porcelain. As a modifier, imperial implies saturation combined with the institutional weight of a color owned by a court. Sits in the bold-and-deep corner, alongside royal.

Tampopo
noun

The Japanese word for dandelionTaraxacum officinale, the cosmopolitan composite-family wildflower whose bright yellow heads dot Japanese spring lawns. Tampopo is also the title of a 1985 Itami Jūzō film about a ramen quest. The color refers to a fresh tampopo bloom: a saturated, slightly red yellow with the matte finish of small ray-florets.
