Better CSS color is now safe to use

In November 2025, a batch of modern CSS color features crossed into Baseline Widely available status, the web platform's way of saying a feature has been stable across every major browser long enough to trust in production without fallbacks. The list includes color-mix(), oklch(), oklab(), the color() function, and the wider Lab and LCH color spaces.

This is quieter than a flashy framework launch, but it's the kind of thing that improves real sites. oklch() lets you define colors that stay perceptually consistent, so a hover state or a tint generated in code looks right instead of muddy. color-mix() lets you blend two colors directly in CSS, cutting down on hand-maintained color variables.

For a business site, this means your developer can build a cleaner, more maintainable color system without shipping extra code to patch old browsers. If you're planning a refresh or a rebrand, it's a good moment to ask whether your palette is defined in a way that will age well. The tools to do it properly are now standard.
