A color palette generator turns one base color into a set of colors that look right together by following the rules of color harmony. The generator below takes a color you choose and a harmony scheme, then builds a five-color palette in your browser by rotating the hue or varying the lightness on the color wheel. Nothing is uploaded, and the palette updates the moment you change the color or scheme.
What a Color Palette and a Color Scheme Are
A color palette is the fixed set of colors a design uses, such as the colors of a website, a logo, or a slide deck. A color scheme is the rule that decides how those colors relate to each other on the color wheel. The color wheel arranges hues in a circle, so every hue has a numeric position measured in degrees. A scheme picks other colors by their angle from the base, which is why a palette built from a scheme reads as deliberate. This tool reads the base color, converts it to its hue, saturation, and lightness, applies the scheme, and converts each result back to a hex code you can paste into any design program.
How to Use the Color Palette Generator
- Open the color picker and choose a base color, or type a hex code if your picker allows it.
- Choose a scheme. Start with Complementary or Analogous if you are not sure which to use.
- Read the five swatches. Each one shows its hex code so you can copy the exact value.
- Copy the hex codes from the list below the swatches into your design tool.
- Change the base color or scheme to explore variations until the palette fits the project.
The Color Harmony Schemes
| Scheme | What it is |
|---|---|
| Complementary | The base hue paired with the hue directly opposite it on the wheel, 180 degrees away. It creates the strongest contrast, which makes one color stand out against the other. |
| Analogous | The base hue plus the hues next to it, about 30 degrees on each side. The colors blend smoothly because they sit close together, giving a calm and unified look. |
| Triadic | Three hues spaced evenly around the wheel, 120 degrees apart. It stays balanced while still offering contrast, which suits designs that need more than two colors. |
| Monochromatic | A single hue at several lightness levels. There is no hue contrast at all, so the palette feels consistent and is hard to get wrong. |
Using a Palette in a Design
A common way to apply a palette is the 60-30-10 rule. One color fills about 60 percent of the design as the dominant background, a second color covers about 30 percent as the supporting tone, and a third color takes about 10 percent as the accent for buttons, links, and highlights. A five-color palette gives you the three working colors plus two extras for borders, shadows, or secondary states. Keeping the proportions consistent is what makes a small set of colors feel like a complete design system rather than a list of swatches. For finer adjustments to a single color, the color picker shows exact hue, saturation, and lightness values.
Palettes and Contrast
A harmonious palette is not automatically a readable one. Text needs enough contrast against its background to stay legible, and color accessibility guidelines set a minimum contrast ratio of 4.5 to 1 for normal text. Schemes that vary lightness, such as monochromatic and shades, make it easy to pair a dark color with a light one for safe text contrast. When you use a complementary or triadic palette, check that any color carrying text sits far enough in lightness from its background, since two colors can harmonize on the wheel yet still be hard to read together.
When to Use a Color Palette Generator
Reach for a palette generator at the start of any visual project: a website theme, a brand identity, a presentation, a chart, or a room of UI components. It is most useful when you already have one color in mind, such as a brand color or a color pulled from a photo, and need the rest of the set to match it. Starting from a scheme saves you from guessing and gives you a defensible reason for each color, which matters when a team has to agree on a look.
Last Thoughts on Generating Color Palettes
A good palette is rarely the product of inspiration. It comes from one color and a rule applied consistently. By turning the color wheel into simple hue math, a generator removes the guesswork and hands you a coordinated set in seconds, so you can spend your time on layout and content instead of trying random colors.
Pick a base color, try each scheme, and copy the palette into your next design. To fine-tune a single color, use the color picker, to name a color you already have, try hex to color name, and to turn two colors into a background, see the CSS gradient generator.

Key Takeaways:
- A palette generator starts from one base color and derives the rest using a color harmony scheme.
- Schemes are hue rotations on the color wheel: complementary adds 180 degrees, triadic uses 120, analogous uses 30, and monochromatic or shades change lightness instead of hue.
- The tool converts your base color to hue, saturation, and lightness, applies the scheme, and converts each color back to a hex code.
- Apply a palette with the 60-30-10 rule: one dominant color, one supporting color, and one accent.
- Harmony does not guarantee readability; keep at least a 4.5 to 1 contrast ratio for text.
- The whole palette is built in your browser, so nothing you enter is sent anywhere.
Frequently Asked Questions (FAQs)
What is a color palette generator?
It is a tool that takes one base color and produces a set of related colors that work together. It does this by reading the base color’s position on the color wheel and applying a harmony scheme, such as complementary or analogous, to find the other colors.
Which color scheme should I choose?
Use analogous or monochromatic for a calm, unified look, complementary when you want one color to stand out, and triadic when you need a balanced set of three distinct colors. If you are unsure, start with analogous, since neighboring hues are the hardest to get wrong.
How many colors should a palette have?
Most designs work well with three to five colors: a dominant color, a supporting color, an accent, and one or two extras for borders or states. This generator produces five colors so you have the working set plus room to spare without overwhelming the design.
What is the difference between a palette and a scheme?
A palette is the actual list of colors a design uses. A scheme is the rule that decides how those colors relate on the color wheel. You apply a scheme to a base color, and the colors it produces become your palette.
Are these palettes accessible for text?
Harmony and readability are separate. A palette can look balanced yet still place text on a background that is too close in lightness. Aim for a contrast ratio of at least 4.5 to 1 for normal text, and pair a dark color with a light one when a color carries words.
Can I use these colors in CSS?
Yes. Each swatch shows a standard hex code, such as #9B59B6, which you can paste directly into CSS, design programs, or any tool that accepts hex colors. Copy the codes from the list below the swatches.
