Start with one color.
Derive the system.

Calm consumer products, health, benefits, and personal utilities

Let warm neutrals carry most of the canvas. Use green for the primary action and current-state reassurance; coral is a restrained supporting accent unless an approved content or brand role calls for greater emphasis.

Creative work, focused productivity, and high-craft prototypes

Use lime for selection and one decisive action, never as body text. Layer chrome one step lighter than the canvas; let generated imagery remain low-luminance.

Developer platforms, data products, and operational workbenches

Use neutral layers for evidence and cobalt for action/selection. Violet belongs to secondary categorization, not a second primary action.

Commerce, hospitality, booking, and human service brands

Let product imagery and warm paper carry identity. Clay marks purchase intent; violet is reserved for saved or personalized context.

Public services, regulated applications, and consequential workflows

Use blue for institution and primary action, green only for confirmed success, and amber focus with a visible outline. Pair every status with text.

Research, journalism, reports, and authoritative reading

Use ink and paper for the reading field. Red marks editorial emphasis sparingly; blue owns links and focus.

Expressive launches, social products, and consumer discovery

Let coral own the hook and selected moment. Violet supports spatial or media context; never let both compete as primary actions.

Media, AI, experimental professional tools, and immersive utilities

Use violet for primary control and mint for creation/progress. Keep media dark enough to preserve chrome and avoid synthetic AI-glow overload.
