Sure Tuscan
Sure Tuscan (#E1F1AA) is a soft yellow with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (74°, 72%, 81%) 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 indigo. 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.
Of Toscana, the central Italian region whose pale ochre stucco and warm terracotta roofs define a regional palette. The color Tuscan yellow refers to the limewash of Florentine and Sienese palazzo facades — a soft, slightly muted gold that's warmer than cream and lighter than honey. The pigment is the same iron-rich earth that gives sienna its name; mixed with lime, it ages to the patina of half a millennium.

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.
