Color Wheel
Drag on the wheel to pick a color, or type a hex code — pick a harmony type to see its complementary, analogous, triadic, or tetradic matches instantly.
Is the Color Wheel Right for Your Project?
Use the wheel for
- •Building a full palette from a single starting color (a logo color, a brand hex you already have)
- •Picking a high-contrast accent color for buttons, alerts, or calls-to-action
- •Exploring options before committing to a final palette, instead of guessing
- •Learning or teaching basic color theory with real, adjustable examples
- •Generating a quick color scheme for illustration, packaging, or textile design
Look elsewhere for
- •Converting a color you already have between formats — use Hex to RGB or RGB to Hex
- •Checking if text is readable against a background — use the Contrast Checker
- •Extracting colors from an existing photo or design — use the Image Color Picker
Who Uses a Color Wheel
Brand and graphic designers use it to build a palette around a single starting color rather than guessing at combinations. UI/UX designers use it specifically for accent and call-to-action colors, since an interface with too many unrelated hues feels unplanned. Interior and fashion designers use the same wheel logic — the math doesn't change whether the output is a hex code or a fabric swatch. It's also a standard teaching tool: color theory is easier to grasp by dragging a marker and watching the relationships update than by reading a definition.
How Color Harmonies Work
Every hue sits at a specific angle on the wheel, from 0° to 360°. Color harmony rules are really just fixed angular offsets from your chosen hue — the tool computes each harmony type by rotating around the wheel and reading off the color at the new angle, at the same saturation and lightness as your base color.
This is the same computation used on Colortion's individual color pages — the wheel is a faster, visual way to explore the same relationships interactively instead of reading them off a single fixed color.
Comparing the Four Harmony Types
Side-by-side so you can pick by contrast level and difficulty, not just by name.
| Harmony | Angles | Contrast | Best For |
|---|---|---|---|
| Complementary | 180° | High | Single accent colors, CTAs, sports branding |
| Analogous | ±30° | Low | Cohesive backgrounds, nature and wellness themes |
| Triadic | 120° apart | Medium–High | Playful brands, illustration, logos |
| Tetradic | 60° / 180° / 240° | Highest variety | Editorial layouts, complex data visualizations |
Which Harmony for Which Project
A starting point if you already know what you're building — pick a row, set that harmony type above, and adjust from there.
| Project Type | Recommended | Why |
|---|---|---|
| Website or app UI | Analogous + one Complementary accent | Calm interface with one clear high-contrast action color |
| Brand identity / logo | Triadic | Distinctive and memorable without feeling chaotic |
| Editorial / magazine layout | Tetradic | Enough variety to differentiate sections and categories |
| Nature or wellness branding | Analogous | Mirrors real-world gradual color transitions, feels organic |
| Sports or energy brand | Complementary | Maximum visual punch, easy to read from a distance |
| Data visualization / charts | Triadic or Tetradic | Needs several colors that stay clearly distinguishable |
| Wedding or event palette | Analogous | Soft, cohesive look that photographs well together |
Frequently Asked Questions
What is a color wheel used for?
A color wheel arranges hues in a circle in the order they appear in the visible spectrum, which makes it easy to spot color relationships — complementary colors sit opposite each other, analogous colors sit next to each other, and so on — that would be hard to judge just by looking at a list of hex codes.
What is the difference between complementary, analogous, triadic, and tetradic?
Complementary is a single color directly opposite the base on the wheel (180°) — high contrast, often used for accents. Analogous colors sit close together (±30°) for a harmonious, low-contrast palette. Triadic uses three colors evenly spaced (120° apart) for a balanced but vibrant combination. Tetradic uses four colors in two complementary pairs (60°, 180°, 240°) for the most variety.
Why does moving the lightness slider not change the wheel's colors?
The wheel itself always displays hue (angle) and saturation (distance from center) at a fixed lightness so the color relationships stay easy to read — this matches how most color-wheel tools work. The lightness slider adjusts the actual picked color and every swatch below the wheel, independently of the wheel's reference display.
Is this the same as HSL or HSB/HSV?
The wheel's two axes — hue as angle, saturation as radius — follow the same convention as HSB/HSV color pickers (like Photoshop's), which is the most common layout for an interactive color wheel. The color values this tool outputs are standard hex/HSL, compatible with CSS and every design tool.
When should I use a color wheel instead of just picking colors I like?
Use it whenever you need more than one color to work together and don't already have a reference to match — a new brand palette, a website's accent colors, an illustration's color scheme. Colors picked by eye without a system often clash or feel arbitrary; a wheel-based harmony guarantees the colors have a mathematical relationship, which reads as intentional even to viewers who couldn't say why it works.
Can I use this for web design or app UI?
Yes — pick your primary brand or background color first, then use Analogous for supporting UI colors (cards, secondary buttons) or Complementary for a single high-visibility action color (primary CTA buttons, alerts). Always run the final pairing through the Contrast Checker before shipping, since a harmony relationship on the wheel says nothing about WCAG text contrast.
