Color palette generator
Generate a coordinated palette from a single base color.
The color palette generator takes a base color and a classic color-theory scheme (complementary, analogous, triadic, or monochromatic) and produces a small set of coordinated colors, each one click away from being copied as a hex code.
How to use
- Pick a base color and a scheme (complementary, analogous, triadic, or monochromatic).
- The palette updates live — click any swatch to copy its hex code.
Common use scenarios
- Finding a few coordinated colors to start a design from a single brand or favorite color.
- Exploring different color relationships around the same base hue.
- Getting quick hex codes for a palette without a full design tool.
- Comparing how different classic color schemes look built from the same starting color.

How we verify Color palette generator
How to confirm the generated palette suits your actual use.
Each scheme follows a fixed color-theory formula
Complementary uses the opposite hue; analogous uses hues near the base; triadic uses hues evenly spaced around the color wheel; monochromatic varies only the lightness of the same hue — these are standard, mechanical relationships, not a judgment about which colors look best together for your specific use.
This doesn't check contrast or accessibility
The generator produces color relationships only — it doesn't calculate contrast ratios or check whether a color pairing is readable as text on a background; verify that separately if the palette will be used for text or UI elements.
The base color's saturation and lightness carry through the scheme
Complementary and triadic schemes keep the same saturation and lightness as your base color, just at different hues — if your base color is very muted or very bright, the generated colors will share that same quality.
Before you rely on the result
- You've tried a couple of different schemes to see which fits your project's mood.
- If the palette is for text or UI, you've separately checked contrast and accessibility.
- You understand the generated colors follow a fixed formula, not a curated aesthetic judgment.
- You've copied the hex codes you need before navigating away, since nothing is saved.
Who this is for
- Anyone finding coordinated colors to start a design from a base color.
- People exploring different color relationships around the same hue.
- Anyone wanting quick hex codes without a full design tool.
- People comparing how different schemes look from the same starting color.
Real-world examples
Starting a design from a brand color
A designer with a single brand color generates an analogous palette to find a few harmonious supporting colors for a layout.
Exploring scheme options
Someone unsure which color relationship to use tries complementary, triadic, and monochromatic from the same base color to compare the moods each one creates.
Quick hex codes for a mockup
A person building a quick mockup picks a base color, generates a palette, and copies each hex code directly into their design tool.
Limitations
- This applies standard color-theory formulas mechanically — it doesn't guarantee the result looks good for every base color, and doesn't check contrast or accessibility for text/background use.
Frequently asked questions
Which scheme should I pick?
It depends on the mood you want — complementary gives high contrast, analogous feels harmonious and calm, triadic is vibrant and balanced, and monochromatic is subtle and cohesive. Try a few to compare.
Does this check if the colors are accessible together?
No — it only generates color relationships based on hue, saturation, and lightness math; contrast ratios and accessibility need to be checked separately, especially for text on a background.
Why do my generated colors look similarly muted or bright?
Complementary and triadic schemes keep your base color's saturation and lightness the same, only changing the hue — a muted or vivid base color produces a palette with that same overall intensity.
Is the palette saved anywhere?
No — copy the hex codes you want before leaving the page, since nothing is stored after you navigate away.
