Color Palette Generator
Generate 5 harmonious colors from a random or custom base color. Click any swatch to copy its hex code.
What Is a Color Palette Generator?
Choosing colors that work together is the invisible hard part of every design project — a website, a presentation, a bedroom wall. A palette generator removes the guesswork: give it a base color (or let it pick a random starting point) and it builds a coordinated set of colors around it, shown as swatches with their hex codes ready to copy. Designers use palettes to keep branding consistent; everyone else uses them to avoid the particular chaos of five favorite colors that refuse to live together.
Good palettes are not random collections of pretty colors — they are relationships. Colors across the wheel from each other (complements) create energy and contrast; neighbors (analogous colors) create calm and unity; tints and shades of a single hue create depth without risk. A generator explores those relationships faster than any human dragging a color picker, which is why the standard workflow is: generate widely, shortlist ruthlessly, then test the survivors at real sizes, on real screens, next to real text.
How to Use the Color Palette Generator
- Enter a base color you want to build around — or leave it empty for a random start.
- Click "Generate Palette."
- Browse the swatches and note the hex codes of the colors you like.
- Generate again for fresh combinations; copy your chosen hex values into your design tool, CSS, or notes.
Using a Palette Like a Designer
Assign roles, not just colors: a typical working palette needs a primary (your brand's main voice), a secondary or accent (used sparingly, for calls to action), neutrals (backgrounds and text carry 90% of most designs), and tints/shades of the primaries for hover states, borders, and depth. The 60-30-10 rule from interior design transfers directly: roughly 60% dominant neutral, 30% secondary color, 10% accent. And always check text contrast — a beautiful pair that fails readability (light gray text on a pastel ground) fails, full stop; accessibility guidelines call for a contrast ratio of at least 4.5:1 for body text.
Hex Codes, Decoded
- A hex code like #3B82F6 is three numbers in base 16: red 3B, green 82, blue F6 — each from 00 (none) to FF (full 255).
- Shorter hex (#FFF, #000) is shorthand where each digit doubles: #FFF means #FFFFFF.
- Save palettes with their hex codes in your project notes — screenshots shift colors; hex values are exact.
How do I copy a palette into my website's CSS?
Copy each hex code and assign it to a CSS variable in your stylesheet — for example: :root { --primary: #3B82F6; --accent: #F59E0B; } — then reference the variables throughout (color: var(--primary)). Centralizing colors this way means a future rebrand is a five-line edit instead of a hundred scattered changes, and it keeps every page perfectly on-palette.
What if I don't have a base color in mind?
Start random and react. Generate several palettes, save any that produces a feeling matching your project (calm, premium, playful, urgent), and then refine from the best one by feeding its strongest color back in as the base. Color direction often emerges faster from judging finished combinations than from imagining a single perfect starting hue.
How many colors should a palette have?
For most projects, five is plenty: two primaries/accents and three neutrals or supporting shades. More than that invites inconsistency — every additional color is a decision every future screen must re-make. Professional brand systems sometimes define more (with strict usage rules), but as a working rule, a tight palette used consistently beats a rich palette used loosely.
Why do the colors look different on my phone and monitor?
Screens render color differently: panel types, brightness, color profiles, and night-mode filters all shift what you see, and uncalibrated displays vary widely. This is precisely why professionals communicate color as hex values rather than "the blue from that screenshot." For print, expect a bigger shift (screens emit light, paper reflects it) and proof on paper before committing.
