linear-gradient(in oklab, ...)), the browser computes transitions in a perceptually uniform space where lightness and chroma are preserved naturally, resulting in vibrant, photorealistic gradients without dull middle colors.
- Linear Gradients: Radiate color along a directional axis defined by degrees or directions. Ideal for hero section backgrounds, primary call-to-action buttons, and cards.
- Radial Gradients: Originate outward from a center focal point in circular or elliptical geometry. Best suited for subtle spotlight illumination, ambient glows, and dark-mode backdrop vignettes.
- Conic Gradients: Rotate color transitions around a central 360° pivot (like colors on a color wheel). Perfect for circular progress indicators, holographic sheen effects, metallic finishes, and pie charts.
in oklab are supported in all evergreen browsers (Chrome 111+, Safari 16.2+, Firefox 113+). For legacy clients, such as older WebViews or HTML email rendering engines (Outlook/Thunderbird), our code exporter provides standard solid color fallback rules (background-color: #hex) and standard sRGB fallback declarations so your UI never renders blank.
