Never the sole carrier of an alarm, unit, limit, mode, relation, or quality state.Established systems need bounded places where new capability can attach, prove itself, and become infrastructure.
Lead body copy. Sustained reading in the unified proportional family.A module changes its track span when capacity changes. It does not scale below its useful content width. The frame preserves the relation between content and the larger system.
Default body copy.Use for dense notes and supporting prose when the measure remains short.
Minimum body copy.COLOR
Alarm priority, validation error, destructive action, selection, live process, success, disabled state, and normal state are independent semantic channels. Consequential meaning always includes exact text and a non-color cue.
| MEANING | COLOR | INDEPENDENT SIGNIFIER |
|---|---|---|
| LIVE EXCHANGE | BASE0C / BLUE | DOTTED DIRECTIONAL ROUTE + LIVE |
| VERIFIED RECOVERY | BASE0B / BLUISH GREEN | SOLID CHECK + RECOVERED |
| CAUTION | BASE09 / ORANGE | TRIANGLE + CAUTION |
| WARNING | BASE0F / VERMILLION | DASHED INTERRUPTION + FAILED / PARTITIONED |
| VALIDATION | BASE08 / REDDISH PURPLE | CROSS + COMPLETE FRAME + INVALID |
Primary interactive background. Absolute black.
STATUS / APPROVEDPrimary text on light records and rare inset material.
STATUS / APPROVEDInactive material and recessed structure. Never ordinary text.
STATUS / RESTRICTEDDisabled state only. Never ordinary body text.
STATUS / RESTRICTEDSecondary frame, inactive rule, or construction annotation. Not body text.
STATUS / APPROVEDPrimary dark-state text and frame member.
STATUS / APPROVEDHigh-contrast neutral emphasis. Not a separate title color.
STATUS / RESTRICTEDDocument, print, and inverted active-pane surface.
STATUS / APPROVEDInput, schema, or local validation error. The muted rose-purple differs from alarm priority and destructive action. Exact INVALID text remains mandatory.
STATUS / APPROVEDConventional caution amber. Operational profile only. Pair with CAUTION text and a distinct marker.
STATUS / OPERATIONALHighlight for hover, focus, selection, checked choices, and current local state. Use in bounded areas.
STATUS / APPROVEDHealthy growth, success, continuity, or verified recovery.
STATUS / APPROVEDLive route, exchange, data flow, or computation in progress. Never a generic active, selected, focus, or hover color.
STATUS / APPROVEDDamage, interruption, or destructive action. This deep brick action role is not an operational alarm classification.
STATUS / APPROVEDOperational advisory blue-gray. Pair with ADVISORY text and a distinct marker.
STATUS / OPERATIONALRestrained vermillion warning. Operational profile only. Pair with WARNING text and an interrupted or shaped marker.
