Pragmatic Spark Teal

#43baa5
Notes

Pragmatic Spark Teal (#43BAA5) is a true teal 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 (169°, 47%, 50%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Pragmatic
adjective

Greek pragmatikós, of business / practical — adjectival suffix -ic. As a color modifier, pragmatic implies a clear-and-purpose-fit-and-no-nonsense quality where the hue carries the visual register of straightforward-utilitarian-and-functional decision-making. Sits at the crisp-and-functional end of the grid, parallel to practical and functional in usage.

Spark
modifier

Old English spearca, small-ember. As a color modifier, spark implies a small-bright-and-flying-ember quality, the visual register of blacksmith-anvil-and-bonfire-spark hand-small-bright-and-flying-ember blacksmith-anvil-and-bonfire-and-flint-strike sparked-and-small-bright-and-flying surfaces under blacksmith-anvil-and-bonfire-and-flint-strike orange-glow-and-iron-and-flint forge-and-hearth-light. Sits at the modifier-and-mood end of the grid, parallel to flash and flare in usage.

Teal
noun

Anas crecca, the small dabbling duck whose male in breeding plumage sports a chestnut head crossed by a glossy green-blue stripe. The color refers to that stripe — the iridescent panel just behind the eye: a saturated, slightly muted blue-green with the optical depth of structural color rather than pigment. Cooler than cypress, warmer than cerulean, with the ornithological specificity of a color named for one feather of one bird.
