Sure Cardenal
Sure Cardenal (#CEC2E9) is a soft indigo with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (258°, 47%, 84%) places it in the balanced band at a light lightness. It works as a background wash, large-area fill, or soft illustration tone. Add a darker ink of the same hue when you need type over it. For a confident two-color system, pair it with its complementary lime. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old French seur, certain — used as a color modifier since the medieval period for hues that read as confident and stable. Sure red, sure blue: moderate saturation combined with optical commitment. Sits at the crisp-bucket center alongside steady and true.
Spanish for cardinal — both the ecclesiastical office and the Lobelia cardinalis (cardinal flower) of New World gardens. The Spanish cardenal hat is technically deep red, but the color name slipped into Hispanic-American color terminology for the violet-tinted purples of cassocks. Cardenal color refers to a Spanish capa magna cardinal-cassock: a saturated, slightly cool deep violet with the matte finish of multi-bath ecclesiastical wool.

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.
This color sits well within the sRGB cube. P3 and sRGB share the gray axis and most desaturated tones, so a P3 display renders this identically to an sRGB display.
