Disciplined Glaucium
Disciplined Glaucium (#6898DF) is a true azure with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (216°, 65%, 64%) 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
Latin disciplīna, teaching / training — past-participle of discipline. As a color modifier, disciplined implies a clear-and-controlled-and-careful quality where the hue carries the visual register of careful-edited-and-restrained design-decision. Sits at the crisp-and-orderly end of the grid, parallel to methodical and orderly in usage.
The genus Glaucium — horned poppy, Mediterranean coastal-dune annuals with silver-blue foliage and yellow or orange flowers. The genus name traces to the same Greek glaukos as glauque (gray-blue-green). The color refers to mature Glaucium flavum foliage: a soft, slightly cool deep silver-blue with the matte finish of waxy-cuticled coastal-dune leaf.

Accessibility
How this color appears to viewers with the four major color-vision-deficiency types. Computed via the Machado (2009) physiologically-based model. If a tile matches the original, the color reads the same to that viewer.
The color used as foreground text against pure white and pure black, with the contrast ratio and WCAG 2.1 grade. Aim for AA (4.5:1) for body text and AA Large (3:1) for 18 pt+ headlines; AAA (7:1) is the gold standard for long-form reading surfaces.
Wide gamut
The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.
Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
