Tissue Niebieski
Tissue Niebieski (#C4E8FB) is a soft azure with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (201°, 87%, 88%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old French tissu, woven-cloth — adjectival usage of tissue. As a color modifier, tissue implies a pale-and-thin-and-translucent quality, the pale color of Edwardian-period fine-tissue-paper gift-wrapping-and-archival-protection thin-and-translucent paper-finish. Sits at the pale-and-thin end of the grid, parallel to onionskin and glassine in usage.
The Polish word for blue — used for the deep blue of Polish folk-embroidery and the niebieski sash of Polish Order of the White Eagle. The color refers to a niebieski-dyed Polish folk costume: a saturated, slightly cool deep blue with the matte finish of dyed wool. The Slavic cousin of blue.

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.
