Origin From Nahuatl. The name is most often glossed as "place of the giant reeds" or "place where the reeds were destroyed/washed away" — referring to the reeds historically growing in the bay area. The Spanish kept the place name; the modern color was popularized through 20th-century travel imagery as Acapulco grew into an international resort destination.

Decorator’s Note A vacation-y, optimistic color. Often used effectively on cabinetry, painted furniture, or a single accent wall in a kitchen or bathroom. In dark or low-light rooms it can read flat; the color benefits from natural light.

Pairs Well With Often paired with terracotta tile, warm sand, and unbleached linen. For a sharper palette, with bright white and bleached wood. Lime green or chartreuse tend to cancel out Acapulco's blue undertones.

Origin Named for the visual impression rather than any chemical acid — a green so saturated it reads as almost corrosive. The term gained currency in 1960s counterculture (where "acid" referred to LSD), and the name attached firmly to the high-saturation chartreuse-green family through subsequent decades of subcultural design.

Famous Uses A defining color of late-1960s psychedelic concert posters; later strongly associated with 1980s Memphis Group design (founded by Ettore Sottsass in 1981) and with the visual identity of acid house and rave subculture in the late 1980s and 1990s. The hue family has cycled in and out of mainstream fashion repeatedly since.

Decorator’s Note A bold accent for the brave — rarely effective as a wall color, but often striking in small doses. A single acid-green velvet armchair or a single neon art piece can transform a neutral room. Often described as reading best against white walls and dark wood floors.

Pairs Well With Most iconic alongside hot magenta for full Memphis-or-rave energy. For a more contemporary take, with charcoal gray, cream, and a single touch of black. Other yellow-greens or oranges tend to compete with it.

Cultural Meaning Across subcultural history, often used to signal defiance, energy, and the artificial — a color that doesn't exist comfortably in nature. In safety contexts (hi-vis vests, hazard signage), the same hue family is widely used as a "look at me — there's danger here" attention-getter.

Decorator’s Note A useful "barely there" tint for trim, painted millwork, and accent walls in white-dominant rooms. Often described as fresh in north-facing rooms; in warm incandescent light it can appear muddy.

Famous Uses Alien Armpit is one of sixteen colors in Crayola's Silly Scents 16-pack (2006), which renames standard Crayola hues with playfully grotesque labels: Big Foot Feet (tan), Booger Buster (spring green), Mummy's Tomb (gray), Ogre Odor (red orange), Sasquatch Socks (violet red), and others. The line was relaunched as scented twistable crayons, markers, and colored pencils in 2017. The name is unrelated to Crayola's 2017 dandelion-replacement contest, which produced the standard-line color Bluetiful.

Famous Uses The 2019 redesign moved deliberately away from the original yellow-green (see Android Green (Classic), #A4C639) toward this more blue-leaning shade, which Google said was chosen partly to be more legible for people with red-green color-vision deficiency, the most common form of colorblindness. In late 2023 the bugdroid mascot was redrawn as a fully 3D capsule-bodied figure; at CES in January 2024 Google revealed that the new 3D mascot is officially called "The Bot". (The original 2007 flat robot, designed by Irina Blok, was only ever informally known as "Bugdroid" within the Android team.)

Famous Uses The original Android robot was drawn by Google graphic designer Irina Blok and unveiled with the Android platform on 5 November 2007. Blok later said she chose the yellow-green deliberately for its echo of monochrome-monitor green-phosphor text and because it would stand out against dark backgrounds. The color was retired by Google as the official brand green in 2019 in favor of the more accessible #3DDC84, but #A4C639 remains widely associated with classic Android logo art and merchandise from the platform's first decade.

Famous Uses Worcester apple-green-ground porcelain — opaque, thickly applied, and gilded around its outline (gold could not adhere to the apple-green pigment itself, so gilders worked around it) — was a signature production of the factory in the 18th and early 19th centuries. The color was originally a Sèvres innovation under royal patronage in France; Chelsea, Chamberlain's, and Flight, Barr & Barr also produced apple-green-ground pieces.

Origin From Latin aqua marina ("sea water"). The stone — a variety of beryl — has been described under similar names in classical sources; Pliny the Elder's Naturalis Historia (c. 77–79 CE) treats it among the beryls. The English color-word entered general use during the 16th century.

Famous Uses The traditional birthstone of March. Widely associated with sea water, with calmness, and with the pale blue-green of beryl gemstones — the meaning a 16th-century buyer would also have understood from the Latin name.

Decorator’s Note A natural fit for bathrooms and kitchens, where it reinforces the association with water and freshness. Often used as full walls in north-facing rooms (where it stays cool and crisp); in south-facing ones it can read as washed-out. Frequently paired with raw linen, weathered teak, and unlacquered brass.

Pairs Well With Often paired with coral, warm sand, and crisp white. For a more sophisticated palette, with charcoal gray and pale gold. Mint and seafoam sit too close in hue to read as distinct.

Cultural Meaning In color psychology, frequently described as among the most calming hues, often used in healthcare interiors and meditation apps. Historically associated with the sea and with safe travel.

Famous Uses The U.S. Army formally adopted olive drab as its standard uniform color by War Department General Order Number 81 of 31 December 1902, replacing the earlier blue wool service uniforms. Soldiers began receiving the new olive-drab uniforms from 1906 as stocks of the older blue uniforms were drawn down. American troops wore olive-drab in both World Wars; the famous "Pinks and Greens" officer's service uniform of WWII paired a dark olive-drab gabardine wool coat with light-shade drab ("pink") trousers.

Famous Uses Introduced as a Crayola crayon in 1993 in a 16-color expansion (alongside Cerise, Denim, Mauvelous, Tickle Me Pink, and others) whose names were chosen by entrants in the company's "Name the New Color" contest celebrating Crayola's 90th anniversary.

Origin In the early international motor-racing rules, national racing colors were assigned to entrants — initially through events like the Gordon Bennett Cup (and later codified by the AIACR, the body that became the Fédération Internationale de l'Automobile after World War II). Britain chose green when it first competed in 1902 because the colors it would normally have used (red, white, blue) were already allocated; the dark forest variant was associated with Selwyn Edge's 1902 Gordon Bennett Cup-winning Napier.

Famous Uses Used by Lotus, Aston Martin, Bentley, Jaguar (in Formula One and Le Mans entries), and Bentley Boys racing entries from the 1920s onward. Remains a signature heritage paint option for high-end British sports cars.

Cultural Meaning Across motorsport and car-design vocabulary, signals British heritage, gentleman-driver tradition, and old-school racing pedigree.

Origin Named after Braunschweig (English: Brunswick), the German city where the copper-based pigment was first manufactured commercially in the 18th century. The name was later also applied to mixtures of chrome yellow and Prussian blue that yielded a similar hue.

Famous Uses Widely used through the 19th and early 20th centuries on locomotives and rolling stock (notably the Great Western Railway in the UK), heavy machinery, billiard balls and tables, and on the front doors and railings of Victorian-era British houses. Considered part of the broader British Racing Green family.
