HSL was a half-step. OKLCH is the first browser-native color space that's truly perceptually uniform — and it changes how we should build palettes.

(Mock post body — in production this is rendered from MDX.) For thirty years designers have built palettes in HSL with the implicit assumption that equal lightness values look equally bright across hues. They don't. A yellow at HSL 50% lightness is dramatically brighter than a blue at the same value, and that gap is why brand systems built in HSL fall apart at scale...

This is a placeholder body for the v1 mock blog. In production this content is rendered from MDX with full embeds (live palette previews, code blocks, contrast checker widgets) and a custom prose renderer that respects The Color Tools design tokens.

The blog ships with category, tag, and author archives, an RSS feed at /blog/rss.xml, and full Open Graph metadata for social sharing.
