Free colour palette generator
A great colour palette is the foundation of a memorable brand and a clean, professional design. This free tool — built by a Singapore branding agency — generates harmonious colour schemes instantly. Pick a harmony rule, set a base colour, lock the shades you love and regenerate the rest, then copy any colour’s hex or export the whole palette as CSS variables. Press the spacebar to keep generating. Everything runs in your browser.
Understanding colour harmony
Harmonious palettes follow relationships on the colour wheel. Analogous schemes use neighbouring hues for a calm, cohesive feel. Complementary pairs opposite hues for high contrast and energy — great for calls to action. Triadic schemes use three evenly spaced hues for vibrant balance. Monochromatic palettes vary the lightness and saturation of a single hue for an elegant, minimal look. Choosing a harmony rule — rather than picking colours at random — is the fastest way to a palette that looks intentional.
Building a brand palette that works
A practical brand palette usually has a primary colour (your dominant brand hue), one or two secondary colours, a bright accent for buttons and highlights, and neutrals (near-black text, off-white backgrounds) for balance. Lock your primary colour above and generate complementary supporting shades around it. Remember the 60-30-10 rule: roughly 60% of a design in your dominant colour, 30% secondary, 10% accent — it keeps interfaces from feeling chaotic.
Don’t forget contrast and accessibility
Beautiful colours still have to be readable. Text needs sufficient contrast against its background to meet accessibility standards (WCAG recommends a contrast ratio of at least 4.5:1 for normal text) — important for users with low vision and increasingly a factor in how professional a site feels. When you pick your final colours, check text-and-background pairs for contrast, and never rely on colour alone to convey meaning. A palette that’s both on-brand and accessible is the mark of considered design.
Turning a palette into a working design system
A set of five pleasing swatches isn’t a system yet. To make a palette usable, assign each colour a role rather than leaving them as equals: a primary brand colour for key actions, one or two neutrals for backgrounds and text, and a single accent reserved for the things you genuinely want people to notice — buttons, links, alerts. The moment everything is a highlight, nothing is. Then expand each core colour into a small scale of tints and shades so you have consistent options for hover states, borders, disabled elements and subtle backgrounds without introducing new hues.
Document the hex values, name them by role rather than by colour (“primary”, not “blue”, so a rebrand doesn’t leave you with a variable called blue that’s now green), and export them as CSS custom properties. That single source of truth keeps your website, decks and social assets in lockstep. If you’re defining these decisions for the first time, our branding services team builds palettes as part of a wider identity rather than in isolation.
How colour choices land in the Singapore market
Colour carries cultural weight, and Singapore’s multicultural audience makes that especially worth thinking about. Red and gold read as prosperity and celebration and appear heavily around festive campaigns; white, elegant in many Western contexts, can also carry mourning associations in some communities. None of this means avoiding colours — it means choosing them with awareness of context and audience rather than on aesthetics alone, and testing key creative with real customers where a campaign hinges on it.
Practicality matters just as much as symbolism. Test your palette against the surfaces it will actually live on — small mobile screens in bright daylight, dark-mode interfaces, and a plain white background — because a combination that sings in a design tool can wash out in the wild. A colour that only works under perfect conditions isn’t a brand colour; it’s a mood board. Choosing hues that hold up across contexts is part of how our web design services keep a brand recognisable everywhere it appears.
Frequently asked questions
How do I create a colour palette for my brand?
Start with one primary colour that reflects your brand personality, choose a harmony rule (analogous or complementary work well), then build supporting and accent colours around it. Lock your primary above and regenerate the rest until the scheme feels right, then export the hex codes.
How many colours should a palette have?
Most brand palettes use three to five core colours: a primary, one or two secondaries, an accent, plus neutrals for text and backgrounds. Too many colours dilute recognition; too few can feel flat.
What is the 60-30-10 rule?
A classic design guideline for balancing colours: use your dominant colour for about 60% of a design, a secondary colour for 30%, and an accent for the remaining 10%. It creates visual hierarchy and stops any one colour overwhelming the layout.
Can I export the palette?
Yes — click any swatch to copy its hex code, or use “Copy all hex” and “Copy CSS variables” to grab the whole palette ready to paste into your design tool or stylesheet.
What’s the difference between RGB, HEX and HSL, and which should I use?
They describe the same colours in different notations. HEX (like #1A73E8) is the compact form you’ll paste into most design tools and CSS. RGB expresses the same value as red, green and blue channels, useful when you need transparency via rgba(). HSL — hue, saturation, lightness — is the most human-friendly for adjusting a colour, because you can nudge lightness to create tints and shades while keeping the hue fixed. Use HEX to store and share, HSL to fine-tune.
How do I check my palette meets accessibility contrast standards?
Compare each text colour against the background it sits on using a contrast-ratio checker, and aim for the WCAG minimums: 4.5:1 for normal body text and 3:1 for large text and meaningful icons. Don’t rely on colour alone to convey information — pair it with text, icons or patterns so colour-blind users aren’t excluded. Building contrast checks into your palette from the outset is far easier than retrofitting them after a design is signed off.
