Technical documentation sites (Stripe Docs, MDN, Tailwind Docs, Vercel Docs) serve users who read for extended periods, frequently switch between prose and code blocks, and need to distinguish syntax elements quickly. The palette must optimize for these specific behaviors.
Reading Comfort
Developers may spend hours in documentation. Body text needs the most comfortable contrast range: dark charcoal on off-white (not pure black on pure white). Line spacing should be generous. The background should be warm enough to avoid the clinical feeling of pure white without being warm enough to tint code blocks.
Code Block Colors
Code blocks need a distinct background (slightly darker or tinted) to visually separate them from prose. Syntax highlighting within code blocks uses a separate palette: keyword colors, string colors, comment colors, variable colors. These should be chosen for maximum distinguishability within the code block context, not necessarily from your brand palette.
Navigation and Wayfinding
Documentation sites have deep navigation trees (sidebar with nested sections). The active section indicator needs to be immediately identifiable: your primary color as a left border, background tint, or text highlight. Hover states on nav items should be subtle (they are dense and users scan rapidly).
Light and Dark Mode
Developers strongly prefer dark mode for reading documentation (it matches their code editor environment). A documentation site without dark mode loses a significant portion of its developer audience. Both modes need fully tested syntax highlighting palettes.
