About Color Palette Generator
Color palettes are a daily need for designers and front-end developers: derive a full swatch set from a brand color, prepare distinguishable colors for data visualization, or define UI state colors. This tool generates complementary, analogous, triadic, split-complementary, tetradic and monochromatic schemes from a base color in HSL space, and outputs HEX, RGB and HSL values for every swatch, exportable as JSON, CSS variables or TXT for direct use in design tools or code. A handy workflow is to lock the primary brand color while regenerating the supporting hues, so you preserve recognition while exploring alternatives without hand-tuning. One nuance to keep in mind: equal hue spacing in HSL does not always feel visually even, so beyond hue it is worth checking lightness and saturation balance across the set, and verifying text/background contrast separately for accessibility. Everything runs client-side, nothing is uploaded — safe even for unreleased brand palettes.

FAQ
Which color schemes are supported?
Complementary, analogous, triadic, split-complementary, tetradic and monochromatic - six schemes in total.
Which input color formats are supported?
HEX (e.g. #1A2B3C), RGB (e.g. rgb(26,43,60)) and HSL (e.g. hsl(210,50%,40%)). You can also pick a color directly with the color picker.
Can I export as CSS variables?
Yes. When exporting as CSS, each color becomes a --color-1, --color-2 custom property, ready to paste into your stylesheet.
How do I ensure accessible, high-contrast palettes?
The tool generates harmonious hues but does not guarantee contrast. Check text/background WCAG contrast separately and verify color-blind friendliness with a vision simulator.
Can I lock the primary and vary only the accents?
Yes. Lock certain colors and regenerate the rest, exploring secondary and neutral combinations while keeping the brand primary intact.
Are colors uploaded?
No. All palette calculations run locally in your browser. Nothing is uploaded, even for unreleased brand colors.
