Color Palette Generator — From Base Color (HEX, HSL, OKLCH)

Guide

About Color Palette Generator

Pick a base color and see complementary, analogous, triadic, tetradic, and monochromatic palettes side-by-side. Each scheme shows 5 swatches — copy any as HEX, HSL, or OKLCH. Use the monochromatic ladder as a Tailwind-style 50-900 scale for design tokens.

Generating palettes from an image, a photo, or a name

Different generators start from different seeds, and it helps to know which this tool is:

From a base color / hex — what this tool does. Paste a hex and get complementary, analogous, triadic, tetradic, and monochromatic schemes with copy-ready HEX/RGB/OKLCH and WCAG contrast.
From an image or photo — extraction tools (and Adobe Color, Canva) sample dominant colors from an uploaded picture. Pull the hex you like with a browser eyedropper, then paste it here to build a full scheme around it.
From a name / brand / theme — “AI” and themed generators (wedding, interior design) map words to a mood. Once you have a seed color you like, this tool turns it into a usable, accessible ladder.

Compared with Canva and Adobe Color, this generator is faster for the color-theory step (harmonies, tonal ladders, contrast checks) and needs no account — it just does not do image sampling or AI theming.

Why generate a palette

Color theory says certain hue relationships work harmoniously. Pulling them out of a wheel manually is tedious; a generator gives you the math without your eye second-guessing it.

Scheme	Logic	Use case
Monochromatic	One hue, varying lightness	Tonal scale, design tokens
Analogous	Adjacent hues on the wheel	Soft, harmonious palettes
Complementary	Opposite hues	High contrast, accent pairs
Split-complementary	Base + 2 near-opposites	Less aggressive than complementary
Triadic	Three evenly-spaced hues	Vibrant, balanced
Tetradic	Four hues, two pairs	Charts, illustrations

Common workflows

Generate Tailwind-style tokens from a brand color. Pick OKLCH monochromatic, copy the 11-step ladder, paste into tailwind.config.js under colors.brand.

Pick chart colors. Tetradic gives you 4 maximally-distinguishable colors. Use for series in a line chart.

Build an accent palette. Analogous gives 5 harmonious colors. Use for tags, status badges, category colors.

Audit accessibility. Each swatch shows WCAG contrast. Pair foreground/background pairs that hit AA.

Why OKLCH for palette generation

HSL palettes look uneven because human perception of lightness varies by hue. OKLCH compensates — equal numerical lightness produces equal perceived brightness. The same logic that makes OKLCH great for variants makes it great for full palettes. The default mode here is OKLCH; toggle to HSL if you need to match a legacy tool’s output.

Frequently asked questions

Which scheme should I use?

Monochromatic is the safest for tokens (a tonal ladder of one hue). Analogous for harmonious accents. Complementary for attention-grabbing contrasts. Triadic and tetradic for multi-color illustrations.

Why does my palette feel muddy?

Generating palettes in HSL gives uneven lightness — a "50% lightness" yellow looks much brighter than "50% lightness" blue. Switch to OKLCH mode for perceptually uniform palettes.

Is there a Tailwind preset?

Yes. The 11-step monochromatic ladder (50, 100, 200, ..., 950) maps directly to Tailwind's color naming. Drop into your tailwind.config.

What is "tetradic"?

Four colors evenly spaced around the wheel — two complementary pairs. Great for charts and data visualization where you need maximum distinguishability.

Can I export the palette?

Copy individual swatches, or copy the whole palette as JSON, Tailwind config, or CSS custom properties.

How accessible is the palette?

Each swatch shows its WCAG contrast against white and black. Use the contrast info to assign foreground colors that pass AA when paired with the swatch.

How do I find the complementary or matching color for a hex code?

Paste your hex as the base color and read the schemes: Complementary gives the single opposite hue, analogous gives neighbors that match, and triadic/tetradic give balanced multi-color sets. Each swatch is copyable as HEX, RGB/HSL, or OKLCH — so it doubles as a hex, RGB, and HTML color finder.

How do I find a color from an image?

To pull an exact color out of an image, use your browser's built-in eyedropper (Chrome/Edge: the color input's picker, or the EyeDropper API) or a screenshot tool that reports the hex under the cursor. Once you have that hex, paste it here as the base color to build a full palette around it. This tool generates schemes from a base color rather than analyzing an uploaded image.
