What this tool does
A brand color set is more than a list of pretty colors; it assigns each color a job. This generator produces a complete identity palette with a primary, a secondary, one or two accents, and a neutral pair for text and surfaces. Each swatch comes with its hex value and a short note on where to use it, so the output drops straight into a brand deck or a stylesheet.
How it works
The generator works in HSL (hue, saturation, lightness) color space because relationships between colors are far easier to control there than in raw hex. It picks a base hue, then derives the other roles using classic color-harmony rules:
- Complementary places the accent 180 degrees opposite the primary on the color wheel.
- Analogous keeps colors within roughly 30 degrees of the base for a calm, cohesive feel.
- Triadic spaces three hues 120 degrees apart for vibrant contrast.
Saturation and lightness are held within tasteful ranges so colors read as professional rather than neon, and a dark and light neutral are generated for body text and backgrounds. The resulting HSL values are converted to hex for output. Everything runs locally in your browser.
Roles in a brand palette
Each color in a well-structured system has a defined job — and mixing up those roles is where most amateur palettes fail:
| Role | Typical use | When to reach for it |
|---|---|---|
| Primary | Wordmark, hero backgrounds, main buttons | The color audiences learn to associate with the brand |
| Secondary | Supporting sections, illustrations, charts | Adds depth without competing with primary |
| Accent | CTAs, badges, highlights, links | Sparingly — one focal point per screen |
| Neutral dark | Body text, headings, outlines | Everywhere text needs to be readable |
| Neutral light | Page backgrounds, card fills | The canvas that lets the other colors breathe |
A worked example
Suppose the tool picks a base hue of 210 (a mid-blue) and uses the complementary rule. A plausible output might look like this:
- Primary
#2563eb— a vivid blue for the main brand surface - Secondary
#3b82f6— a lighter sibling that creates depth without a second hue - Accent
#f59e0b— the complement, an amber, pulled at lower saturation so it pops without fighting the blue - Neutral dark
#111827— near-black for text, derived from the base hue so it feels warm rather than clinical - Neutral light
#f9fafb— off-white for backgrounds, keeping the whole palette coherent
The exact values will vary each time you generate — this is a fabricated illustration of the pattern, not a guaranteed output.
Practical guidance
- Primary covers area, accent covers points. A button, a badge, and a highlighted stat — that is what the accent is for. Spreading it across navigation, cards, and icons dilutes the brand signal.
- Verify contrast before publishing. The neutral dark on neutral light combination should exceed a 7:1 ratio (WCAG AAA) for body text and 4.5:1 (AA) at a minimum. Paste hex pairs into a dedicated contrast checker.
- Store as CSS custom properties. Convert the output immediately into
--color-primary,--color-accent, and so on in your stylesheet. When the brand refreshes, swapping the value at the top of one file is far safer than a global find-and-replace. - Analogous for calm, complementary for energy. Choose the harmony that fits the emotional register of the brand before generating. A legal services firm rarely wants triadic contrast; a gaming company rarely wants monochromatic calm.
- Regenerating changes only the hue, not the structure. Every generated set follows the same role definitions, so nothing is lost by regenerating until the palette feels right.
