IDENTITY / VERSION 1.0 / OCTOBER 2026

Clear authority.
A considered identity.

A precise, calm identity for agents that act in business systems. The shield-R signals an explicit boundary. Violet brings possibility; ink brings clarity.

02 / COLOUR

A restrained, readable palette.

Ink#25283BPrimary text and dark surfaces

Violet#6950C7Identity and emphasis

Ivory#F7F5EFPrimary light surface

Lilac#E6DFF6Supporting light surface

Muted ink#625E70Secondary text on light surfaces

Use ink or muted ink for small copy on ivory and lilac. Use ivory or white on ink. Use violet on ivory for emphasis. Check contrast when pairing colours; pale accent colours are surfaces, not small text. Status must always include a readable label.

03 / TYPE & SPACE

Room for the important part.

Give agents room to work.
Keep control.

Interface and editorial type use the system sans-serif stack: Inter when available, then ui-sans-serif, system-ui, Apple and Segoe UI fallbacks. No remote font request is required. Use ui-monospace for identifiers and technical labels.

The supplied wordmark is outlined from DejaVu Sans Bold and Regular for consistent reproduction. Use the vector master rather than retyping it.

04 / USE WITH CARE

Keep the boundary clear.

Leave at least half the shield’s width clear on all sides. Keep the standalone mark at least 24px wide and the full logo at least 140px wide on screen. For tiny favicons use the supplied mark.

Do

Use an approved light, reverse or mono file.
Keep original proportions and clear space.
Place the logo on a quiet, contrasting surface.

Don’t

Stretch, rotate, recolour or separate the R from its shield.
Add shadows, gradients, borders or extra symbols to the logo.
Place it over busy imagery or imply a certification badge.

05 / VOICE & POSITIONING

Specific. Calm. Accountable.

Explain the action, the boundary and the observable result. Use plain verbs and concrete limits. Sound like a thoughtful technical partner. Describe what exists today separately from what a future integration could support.

SAY

“Give agents authority. Keep control.”

“RuleEvo checks scoped authority before admission in integrated workflows.”

“Withdraw future authority. Reconcile uncertain outcomes.”

“A bounded prototype seeking design partners.”

AVOID

Promises beyond the boundary.

No “every agent must pass through us,” “instant global stop,” “guaranteed undo” or “Google-certified.”

No invented customer logos, independent audits, uptime promises or claims of proven customer demand.

Use “proposed pilot” for the offer. Commercial billing is not enabled.

Clear authority.A considered identity.
