Threadbare Como

#646a7a
Notes

Threadbare Como (#646A7A) is a true azure 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 (224°, 10%, 44%) places it in the muted 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 at the hushed-and-worn end of the grid, parallel to frayed and tattered in usage.

Como
