Resilient Banner

#2b4aab
Notes

Resilient Banner (#2B4AAB) is a true blue with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (225°, 60%, 42%) 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.

Etymology

Resilient
adjective

Latin resiliēns, springing-back — present-participle of resilīre. As a color modifier, resilient implies a saturated-and-recovering-and-flexible quality where the hue maintains its strength under visual pressure. Sits at the bold-and-resilient end of the grid, parallel to tough and hardy in usage.

Banner
noun

A heraldic flag — particularly the deep-blue banner of European nobility and the Star-Spangled Banner (the US flag). Banner color refers to a saturated heraldic azure field: a saturated, slightly cool deep blue with the matte finish of dyed bunting flag fabric.
