Analogous Color Palette Generator

Takes a base hex color and builds a 3-swatch palette from hues adjacent to it on the color wheel: the base hue minus the chosen angle, the base hue itself, and the base hue plus the angle, all at the same saturation and lightness. Rendered as a downloadable PNG strip. A free online tool from Staaarter, right in your browser.

Overview

Introduction

This tool builds a classic 3-color analogous palette from any hex color, using neighboring hues around the color wheel for a naturally harmonious result.

The hue spacing is adjustable, so you can dial in a subtle or a more distinct set of related colors.

What Is Analogous Color Palette Generator?

A generator that converts a base hex color to HSL and produces two neighboring hues, offset by a chosen angle in each direction, while keeping saturation and lightness constant across all three.

The three resulting colors are rendered as equal-width square swatches in a single downloadable PNG, left (base minus angle) to right (base plus angle), with the base color in the middle.

How Analogous Color Palette Generator Works

The base hex color's hue, saturation, and lightness are extracted, then two new hues are computed by subtracting and adding the chosen angle (wrapped into the 0-360 range).

All three hues are converted back to RGB using the same saturation and lightness as the base, then painted into a 3-swatch PixelBuffer.

When To Use Analogous Color Palette Generator

Use it when you want a palette that feels cohesive and low-contrast, such as for a calm background gradient, a nature-themed illustration, or a UI palette that avoids jarring color jumps.

It's also a quick way to explore subtle hue variations around a brand color without drifting into unrelated colors.

Features

Advantages

  • Produces naturally harmonious colors since analogous hues are, by definition, visually related.
  • The adjustable angle lets you control how subtle or pronounced the variation is.
  • All math is exact HSL hue rotation, not an approximate visual guess.

Limitations

  • Analogous palettes lack strong contrast by design; pair with a complementary accent if you need a pop of contrast.
  • Very large angles (near 60 degrees) start to look less 'analogous' and more like an arbitrary 3-hue spread.

Examples

Default 30-degree spread from red

Input

#FF0000, angle=30

Output

Three swatches: a reddish-orange, pure red, and a reddish-pink, all fully saturated

The two side hues sit at 330 and 30 degrees, 30 degrees away from red's hue of 0.

Tight 10-degree spread

Input

#3366CC, angle=10

Output

Three very similar blues, barely distinguishable at a glance

A small angle keeps all three hues visually close together for a subtle gradient effect.

Best Practices & Notes

Best Practices

  • Use a smaller angle (10-20 degrees) for subtle, cohesive gradients and a larger angle (40-60) when you want more visible variety while staying harmonious.
  • Reserve one of the three hues as your dominant color and use the other two as supporting accents.

Developer Notes

Hue offsets are computed with simple modular arithmetic on top of a pure HSL-to-RGB conversion function; no DOM or canvas APIs are touched in the lib file, so the palette logic is fully unit-testable in Node.

Analogous Color Palette Generator Use Cases

  • Building a calm, low-contrast color palette for a background or illustration
  • Exploring subtle hue variations around an existing brand color
  • Generating a natural-feeling gradient of related colors for data visualization

Common Mistakes

  • Expecting a large hue contrast — analogous colors are intentionally close together; use the Complementary or Triadic generator for stronger contrast.
  • Using all three colors with equal visual weight, which can look flat; vary proportions for a more designed feel.

Tips

  • Try angle=15 for the most classically 'analogous' feeling result.
  • Pair an analogous palette with a single complementary accent color for contrast without abandoning the overall harmony.
