Color Palette Tool

Generates cohesive color palettes from a base color using established color harmony rules. The tool targets designers, UI developers, branding teams, and marketing professionals who need rapid, repeatable color schemes that align with brand guidelines. By starting from a single base color, it ensures consistency across interfaces, dashboards, print assets, and digital campaigns. It outputs a list of hex colors ready for use in design systems and CSS tokens.\n
\nConceptually, the tool converts the base color into a perceptual color space (HSL) and applies categorical hue offsets based on the chosen harmony: analogous, complementary, triadic, or tetradic. It preserves relative saturation and lightness, then optionally shifts these attributes to emphasize vibrancy or accessibility. The result is a palette where color relationships are predictable rather than ad hoc, enabling faster iterations and clearer brand expression.\n
\nAdvanced capabilities include optional saturation and lightness deltas, accessibility checks against WCAG contrast thresholds, and the ability to export as CSS variables or JSON for developer tooling. The algorithm clamps values to valid ranges and handles edge cases such as grayscale base colors, where hue offsets have minimal impact but relationships remain defined.\n
\nUse cases span brand refresh planning, UI theming for apps and dashboards, marketing collateral colorization, and asset generation for social media. Its differentiator is a straightforward, math-based approach that preserves color harmony while exposing practical outputs for implementation teams. By combining precise domain logic with export options, it reduces the need for manual palette tweaking and accelerates design-to-code handoffs.
