Beaming Mater Peridot
Beaming Mater Peridot (#4FFAA7) is a true teal with a neon character. It sits at the high-saturation edge of its family. Use it sparingly, as signage, accent, or highlight against darker surfaces. Its HSL profile (151°, 94%, 65%) places it in the highly saturated band at a mid 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
The progressive participle of beam, to emit a directional light — used as a color word since the nineteenth century for hues that read as if focused and projecting. Beaming yellow, beaming pink: the implication is luminance combined with directionality. Sits at the bright-bucket center alongside radiant and glowing.
Latin mater, mother. As a color modifier, mater implies a Latin-mother-and-Stabat-Mater-and-Madonna quality, the visual register of Stabat-Mater-and-Pietà-mater hand-Latin-mother-and-Stabat-Mater-and-Madonna Stabat-Mater-and-Pietà-mater-and-Marian-iconography mater-and-Latin-mother surfaces under Stabat-Mater-and-Pietà-mater-and-Marian-iconography Roman-and-Counter-Reformation Madonna-iconographic-light. Sits at the modifier-and-Latin end of the grid, parallel to pater and amor in usage.
The transparent green variety of olivine — the gem mined from Egyptian Zabargad Island since pharaonic times and now from arid mountain ranges in Pakistan, Arizona, and Vietnam. The color refers to a faceted peridot: a clean, slightly yellow-shifted green with the gem's signature internal warmth. Lighter than emerald, brighter than olivine in its rough state, with the unusual gem-trade quality of being one of the few minerals that occurs in only one color.

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 is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
