What makes a color look neon?

Neon colors push saturation close to its maximum while keeping lightness in the mid-to-high range, so the hue reads as pure and electric. In HSL that is saturation around 95 to 100 percent with lightness near 55 to 65 percent.

How are the harmonies built?

A base hue is chosen at random. Triadic palettes space three hues 120 degrees apart; split-complementary takes the base plus two hues flanking its opposite; random spreads hues freely. Every hue is then pushed to neon saturation and lightness.

Do neon colors work for text?

Rarely on light backgrounds. Neon colors shine brightest against dark or black backgrounds, the classic cyberpunk look. For body text, keep neon for accents and headings and use a neutral color for long passages.

How do I get the glow effect?

The hex codes give the base color; the glow comes from CSS. Apply a colored text-shadow or box-shadow using the same hex with a blur to simulate neon light against a dark background.

What format are the colors?

Each swatch shows a hex code such as #FF1FA6, computed in HSL and converted to hex, ready for CSS and design software.

Neon Color Palette Generator

This generator builds electric neon palettes in the spirit of 80s synthwave and cyberpunk design. Colors are computed in HSL with saturation pushed near its maximum, then converted to hex for direct use.

How it works

A base hue is chosen at random, then related hues are derived by the selected harmony and forced into the neon zone:

Triadic: three hues spaced 120° apart for maximum contrast.
Split-complementary: the base plus two hues flanking its opposite (base +150° and +210°) for a slightly softer tension.
Random: hues spread freely across the wheel.

Every resulting hue is set to saturation 95–100% and lightness 55–65% — the combination that reads as pure, glowing color.

Tips and notes

Neon palettes look their best on dark or near-black backgrounds; pair this with the dark-mode generator for a full cyberpunk theme. To get the signature glow, add a CSS text-shadow or box-shadow in the same hex with a blur radius. Reserve neon for accents and headings rather than body text. Click any swatch to copy its hex code.
