What makes this color different?

Lime is the fully active green primary in sRGB. The CSS keyword lime corresponds to this HEX; the CSS keyword green is a different, darker value.

This HEX also has a CSS keyword name.

Better together.

Complementary

Two colors, 180° apart. A clear contrast across the HSL color wheel.

Analogous

Neighbors at −30°, 0° and +30°. A close-knit family of hues.

Triadic

Three hues at 0°, 120° and 240°. An evenly spaced triangle on the HSL wheel.

A practical design example

Use it sparingly in a dark data display, a sports graphic or an experimental accent. Pair a status marker with a written label so its meaning survives changes in color perception.

Design advice is context-dependent. It is separate from the numeric calculations.

What to check before using it

White lettering on this luminous green is easy to underestimate. Test a dark foreground instead of assuming that all saturated brand colors support white text.

A little theory. A lot to explore.

PALUNEXA rotates hues on the HSL color wheel and keeps saturation and lightness unchanged. Monochromatic palettes vary lightness instead. Harmony is a starting point for design, not a guarantee of aesthetic fit.
