Flashing Coreopsis

#b2c438
Notes

Flashing Coreopsis (#B2C438) is a true yellow with a warm character. It leans warm, pulling light toward red, orange, and yellow. Naturally inviting, it suits editorial and hospitality contexts. Its HSL profile (68°, 56%, 49%) 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 blue. For something softer, pull in its analogous neighbors on either side of the wheel.

Sits at the bright-and-flashing end of the grid, parallel to coruscating and flickering in usage.

Coreopsis
