Interactive Color Wheel

The color wheel uses a CSS conic-gradient to render the full hue spectrum. Clicking anywhere on the wheel calculates the hue angle using Math.atan2. Saturation and lightness are controlled independently with sliders. Color harmonies are calculated by rotating the selected hue by fixed angles: complementary (+180°), triadic (+120°, +240°), analogous (±30°), and split-complementary (+150°, +210°). All computations run entirely in your browser.
