Sure Sencha
Sure Sencha (#B0FBC3) is a soft green with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (135°, 90%, 84%) places it in the highly saturated band at a light lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary magenta. 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.
The Japanese steamed-leaf green tea — the most-consumed Japanese tea, distinct from matcha (powdered) and gyokuro (shaded-grown). The color refers to fresh-brewed sencha in a porcelain cup: a saturated, slightly cool deep blue-green with the optical clarity of steamed-leaf green-tea liquor.
