- Copy Swatches & Export CSS: Click any individual color strip to copy its hex code, or use Copy All or Export CSS to obtain complete
:rootdesign tokens for your stylesheets.
Frequently Asked Questions
What is the difference between complementary and split-complementary color palettes?
A complementary palette pairs a base hue with its exact 180° opposite on the color wheel for maximum contrast. A split-complementary palette pairs the base hue with the two colors adjacent to its complement (at 150° and 210°), providing rich chromatic variety with softer contrast.
What is the 60-30-10 color rule in UI/UX design?
The 60-30-10 rule is a visual distribution guideline: 60% dominant neutral background, 30% secondary structural elements (cards, navigation), and 10% high-contrast accent reserved strictly for primary call-to-action buttons and key highlights.
How do I use the exported CSS custom properties in my project?
Click Export CSS to copy a ready-to-use :root declaration block containing your palette swatches. Paste it into your main stylesheet and apply colors across components using standard CSS variables like background-color: var(--color-1);.
What does an analogous color scheme look like?
An analogous palette features colors situated immediately adjacent to one another on the color wheel (typically spaced by 30°), creating low-tension, tranquil, and cohesive visual designs commonly found in nature.
Can I generate color palettes from my existing brand logo or hex code?
Yes. Use the Base Color picker to input your exact brand hex code. All harmony models (except Random) automatically anchor their geometric color wheel calculations around your primary brand color.
Why does the tool use HSL instead of RGB for color calculations?
RGB coordinates represent hardware light channels that do not map intuitively to human perception. HSL models color as a cylindrical wheel (Hue 0-360°, Saturation 0-100%, Lightness 0-100%), allowing precise angular harmony and luminance stepping.
Is my color palette and brand data secure when using this tool?
Yes, completely secure. All calculations execute 100% client-side inside your browser sandbox in ephemeral memory. No color codes, palette selections, or project data are ever transmitted to any external server.
