Mighty Fairywren
Mighty Fairywren (#473DB7) is a true blue 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 (245°, 50%, 48%) 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 yellow. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old English mihtig, strong — adjectival suffix -y, sharing root with German mächtig. As a color modifier, mighty implies a saturated-and-strong-presence quality, where the hue commands visual attention through pure pigmentation strength. Sits at the bold-and-saturated end of the grid, parallel to forceful and commanding in tone.
Australian Splendid Fairywren (Malurus splendens) — a small Maluridae passerine of arid southern Australia, whose breeding-plumage males are a luminous all-over violet-blue. Fairywren color refers to a breeding-plumage male Malurus splendens in mulga scrub: a saturated, slightly cool deep blue-violet with the iridescent satin finish of structurally colored feather barbs over melanin substrate. Among the most saturated naturally occurring blue-violets in vertebrate plumage.
