Color Palette Generator

This tool generates color palettes from a base color or seed swatches and applies color-theory rules to produce cohesive sets for UI design, branding systems, and marketing assets. It supports typical color inputs (HEX, RGB, and HSL) and validates values, ensuring consistent results across projects. By anchoring palettes to a primary color, it preserves brand voice while enabling quick exploration of harmonies and tonal variations.
Conceptually, inputs are parsed into a canonical color space and a harmony engine computes candidate colors by maintaining defined hue relationships. Supported schemes include complementary, analogous, triadic, tetradic, and monochromatic, with optional constraints for saturation and lightness ranges. The tool then stabilizes color relationships, avoids near-duplicates, and returns a palette in HEX, RGB, and HSL. It also offers CSS variable representations for easy integration.
Benefits: designers, frontend engineers, product managers, and marketing teams gain a repeatable, brand-aligned starting point for UI themes. The approach is deterministic, so two users starting from the same base color receive the same palette; advanced users can seed with multiple colors for richer sets. Unique value includes built-in accessibility checks for contrast and the ability to export tokens and style-ready code.
Core features include multiple export formats, seed support, and a comparison-ready SVG preview. Typical use cases are palette initialization, theme tokens, and rapid prototyping of color-driven UI experiments.
