Visual standard

Sentinel grey, cyan and clean white highlights.

The public website uses the same broad colour family as the Sentinel Linux desktop light theme: dark and mid-tone greys, official Sentinel cyan and highly readable white or soft-grey text.

Visual boundary: the design should feel calm, capable and familiar, not like a hacker terminal, threat dashboard or imitation of another security distribution.

Prefer

Real desktop screenshots, flat icons, sentence-case headings, clear spacing and short explanations.

Avoid

Near-black pages, heavy cyan glow, raw terminals above the fold, cyber-threat imagery and excessive badges.

Keep technical depth

Checksums, manifests and package records remain available in the Trust Centre and developer areas rather than dominating public landing pages.
