Overview
Choosing one colour is easy. Choosing five that can share a page without quarrelling is the job that eats afternoons. Palette generators exist because colour harmony is not a matter of taste alone — it follows geometry. Colours sit on a wheel, and certain arrangements of points on that wheel reliably look balanced to human eyes: neighbours that blend, opposites that spark, triangles that stay lively without tipping into chaos.
This generator does that geometry honestly. You bring a base colour — your brand orange, a client's navy, the green from a photograph — and a harmony rule, and it computes the other four colours on the wheel and along the lightness scale, so the five arrive as a working set: a lead colour, support colours, and enough range in depth to cover backgrounds, text, borders and accents.
What is a colour harmony?
A harmony is a recipe that picks colours by their positions relative to each other on the colour wheel. Analogous schemes take neighbours, which is why nature photography and calm interfaces lean on them. Complementary schemes pair a colour with the one directly opposite, producing the strongest contrast the wheel offers. Triadic schemes space three hues evenly, 120 degrees apart, and stay vivid even when each colour is muted. Split-complementary softens the opposite pairing by taking the two colours either side of the true opposite, and monochromatic schemes keep a single hue and let lightness do all the talking.
None of these is "the right answer". They are starting shapes. A good palette usually keeps the harmony but adjusts individual members — a touch less saturation here, a step darker there — and this page makes that easy because the output is five honest HEX codes you can take anywhere, including into our Colour Studio for fine-tuning.
Features
- Five classic harmonies: analogous, complementary, triadic, monochromatic and split-complementary, computed on the real colour wheel.
- Any base colour: pick it visually or type its HEX code — your brand colour becomes the anchor of the set.
- Five-colour sets: every palette arrives as five balanced swatches with a spread of lightness, not five near-duplicates.
- Click-to-copy cards: each swatch is labelled with its HEX code and copies it when clicked.
- Copy the whole set: one button copies all five codes as a ready-to-paste list.
- Spacebar surprises: tap Space for a new random base colour and a fresh palette — the fastest way to break a creative block.
- No uploads, no account: the wheel maths runs in your browser and nothing is stored.
Benefits
- Harmony by construction: the colours agree with each other because geometry says so, not because you hoped.
- Brand-safe starting points: the base colour stays in the set, so the palette grows out of your identity instead of replacing it.
- Minutes instead of afternoons: a presentable palette in one click, leaving your time for judging rather than hunting.
- Portable output: five HEX codes paste cleanly into CSS, design tools, slides and documents.
- Serendipity on tap: random spacebar palettes regularly surface combinations you would never have chosen on purpose — some of them excellent.
Who can use it
Anyone facing a blank canvas that needs colour: web and app designers starting an interface, small businesses dressing a shop or a slide deck in something coherent, illustrators planning a piece, and developers who need a chart palette that will not embarrass them. It is also a forgiving way to learn colour theory — change the rule, watch the wheel's geometry become five rectangles, and the vocabulary of harmony stops being abstract.
How to use
- Set your base colour with the picker, or type its HEX code.
- Choose a harmony rule that matches the mood — calm (analogous, monochromatic) or energetic (complementary, triadic).
- Click Generate and study the five cards that appear.
- Click any card to copy its HEX code for use in your project.
- Click "Copy all HEX codes" to take the whole set at once.
- Not feeling it? Press Space for a surprise base colour, or change the rule and generate again.
Frequently asked questions
Which harmony should I start with?
If you have a brand colour and a website to dress, analogous and split-complementary are the safest first tries — they give contrast without drama. Triadic is wonderful for illustrations and playful products. Monochromatic suits formal, minimal designs where texture and layout do the talking.
Why do some generated colours look greyish?
When a base colour has low saturation, its relatives inherit that quietness — the wheel maths preserves character. If you want a livelier set, start from a more saturated base colour and the whole family wakes up.
Can I use these palettes commercially?
Yes. Colour combinations are not something this tool licenses or restricts; the codes it produces are yours to use in any project, personal or commercial, with no attribution needed.
How do I turn a palette into a finished design?
A common recipe is 60-30-10: the lightest or most neutral colour covers most space, a supporting colour takes about a third, and the strongest colour is reserved for small accents like buttons and links. Then check your text pairings in the Contrast Checker before you commit.
What does the Space key actually do?
It chooses a new random base hue, updates the picker, and regenerates the palette under your currently selected harmony rule. It ignores the keypress while you are typing in a field, so it never interrupts editing a HEX code.
Are the palettes saved anywhere?
No. Nothing leaves your browser and nothing is written to storage. If a palette wins you over, copy its codes before you close the tab — once it is gone, it is gone.
Conclusion
Five colours that agree with each other are a design's best first decision, and they take seconds when geometry does the picking. Anchor the set in a colour you already love, choose the rule that matches the mood, and deal yourself a palette worth building on.
