Programmatic Color Generation: Algorithms for Dynamic Palettes Generating color palettes in code isn't just a convenience — it's a requirement for anything that personalizes UI by user, tenant, or data. Avatar backgrounds, chart series colors, dynamic theming, procedural maps: all of them need colors that feel intentional even though they're computed. This post covers the algorithms: golden ratio hue distribution, tint/shade step generation, contrast enforcement, and a complete palette factory. All examples are pure TypeScript — no library required. You can verify any output in the color picker tool. Golden Ratio Hue Distribution The golden ratio conjugate is . Multiplying a counter by this value and taking mod 1 produces a sequence that fills any range evenly — each new value lands in…
