A walkthrough of building a user-customizable white-label theme system using Tailwind CSS v4 and the OKLCH color space. The technique generates an entire 11-shade color palette from a single CSS variable (--color-value representing the hue angle), so changing one value recolors the entire app instantly. The setup uses Tailwind's @theme directive with OKLCH color functions, a data-theme style tag in the HTML layout for the default value, and a small Stimulus controller that updates the CSS variable at runtime via a range slider. OKLCH is highlighted as ideal for palette generation because lightness and chroma stay consistent across shades while only the hue changes.
