Fiery Roller

#3fbc55
Notes

Fiery Roller (#3FBC55) is a true green with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (131°, 50%, 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Roller
noun

The family Coraciidae — Old World rollers whose acrobatic flight gives the family its name. Coracias caudatus (lilac-breasted roller) of southern Africa displays saturated turquoise wing covers. The color refers to a male lilac-breasted roller's wing: a saturated, slightly cool deep turquoise.
