Color Wheel Tool

This tool produces color harmony palettes from a single base color. It supports common schemes such as complementary, analogous, triadic, tetradic, and monochromatic, delivering hex codes and optional contrast guidance for readability. The process is deterministic and repeatable, aiding design handoffs and collaboration.
Conceptually, the system converts input colors into a device-independent space, steps through hues around a wheel, and respects user-specified saturation and brightness boundaries. The primary value is reproducibility: two designers starting from the same base color will generate compatible palettes. Accessibility checks surface contrasts that may fail WCAG guidance, helping teams adjust for legibility.
Core features include multiple harmony modes, adjustable palette size (up to 12 colors), hex output, and an export-ready hex list for CSS variables or design tokens. This tool supports quick iterations in branding refreshes, UI theming, and rapid prototyping of color systems.
A key differentiator is the combination of harmony-aware generation with built-in contrast guidance and hex-focused outputs that integrate smoothly into developer workflows. It is designed for designers, frontend engineers, and product teams seeking efficient color strategy without manual trial-and-error.
