Ostentatious Cassis
Ostentatious Cassis (#E690EA) is a soft violet 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 (297°, 68%, 74%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin ostentātiōnis, display — adjectival suffix -ous, derived from ostendere (to show). As a color modifier, ostentatious implies a saturated-and-attention-demanding-and-elaborate quality, the bright color of Belle-Époque-and-Gilded-Age showy-luxury-display interior-decoration. Sits at the bright-and-flamboyant end of the grid, parallel to flamboyant and showy in usage.
French for blackcurrant (Ribes nigrum) — the deep-violet drupe used in Burgundian Crème de Cassis liqueur and Kir aperitif. Cassis color refers to a freshly macerated Ribes nigrum drupe-pulp in a Burgundian Crème de Cassis base: a saturated, slightly cool deep violet with the matte finish of anthocyanin-rich blackcurrant juice. Slightly warmer than Cabernet-style table wine.
