Key facts
The story of this color
Bancha (#646B4A) belongs to the Lime color family.
With a dusty, low-saturation character, this color offers quiet complexity—neither bold nor faded. Dusty tones add vintage charm to retro-inspired designs and pair beautifully with metallic accents like copper or brass.
Lime green emerged as a popular color in the mid-20th century, fueled by psychedelic art and pop culture. The color takes its name from the citrus fruit, and its bright, acidic quality made it a staple of 1960s mod fashion and 1990s rave culture. In nature, lime green appears in new spring foliage, signaling the first stages of growth after winter dormancy.
Lime green projects youthful energy and works well for sports, fitness, and tech brands targeting younger demographics. It pairs effectively with dark purple or navy for bold complementary schemes, or with white for a fresh, clean look. Use lime sparingly as an accent—it can overwhelm when used as a dominant color.
Sitting on the cool side of the spectrum (hue 73°), it promotes a feeling of calm distance and intellectual clarity, which is why cool hues dominate corporate identities, healthcare design, and productivity tools. With only 18% saturation, this near-neutral shade carries just a hint of its underlying hue—subtle enough for large surfaces yet adding more warmth (or coolness) than a pure gray.
Lime stimulates vitality, freshness, and excitement. It sits at the boundary of yellow's optimism and green's natural calm, creating a unique sense of dynamic growth. Lime is particularly effective in contexts where energy and eco-consciousness intersect.
With a mid-range lightness of 35%, this tone is highly versatile: dark enough to serve as body text on white, yet light enough to stand out on charcoal or navy backgrounds.
Use lime as a highlight color for progress bars, success states, and achievement badges in gamified interfaces. Combine lime with matte black for an electric, high-tech brand identity. In packaging, lime accents on white suggest organic freshness—ideal for health drinks and snack brands.
