Resolute Cynoglossum

#374eaa
Notes

Resolute Cynoglossum (#374EAA) 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 (228°, 51%, 44%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Sits in the bold-bucket center alongside strong and true, with slightly more focus on stability than presence.
