Useful progress
Make technology practical enough to improve how people decide, work and grow.
01 · Foundation
One coherent idea behind every Vireo experience.
We make complex systems feel understandable, connected and ready to act on.
Clarity you can trust
Every product and service should reduce uncertainty and reveal the next responsible action.
Calmly capable
Precise, direct, considered and quietly optimistic. Never theatrical, vague or needlessly technical.
01Clarity
Make the complex legible.
02Reliability
Earn confidence through evidence.
03Momentum
Turn understanding into progress.
04Humanity
Technology serves people, not the reverse.
02 · Brand architecture
Vireo leads. Products inherit its trust.
Master brand
Endorsed product familyCollectCashInboxDeskCommerceConnectAssist
Use Vireo alone for the company, culture, partnerships and corporate communication.
Product families retain the Vireo name and add a distinct, purposeful descriptor.
Collect, Cash and other modules use names—not independent logos or color worlds.
New products inherit the master logo, type, spacing and accessibility rules.
03 · Logo system
The original Vireo artwork is the source of truth.
Primary · color on light
Reversed · color on dark
One-color dark
One-color signaturex
Clear space
Keep at least one cap-height x around every side. No text, edge or competing mark may enter this area.
Minimum size
Full logo: 120 px digital / 30 mm print. Symbol: 20 px digital / 6 mm print.
Never compromise the mark
Do not stretch or compress.
Do not outline or add effects.
Do not introduce new colors.
Do not rotate or rearrange.
04 · Color
Corporate recognition and product intelligence, clearly separated.
Vireo core
Use across the company, communications and shared brand moments.
Vireo IQ digital
Midnight is owned by the Vireo IQ product family—not the corporate master logo.
Functional
Meaning comes before branding in status and data communication.
Vireo Red creates recognition; it is not a universal button color. Midnight gives Vireo IQ a composed enterprise presence. Green, amber and critical red are reserved for system meaning.
05 · Typography
Contemporary enough for software, neutral enough for trust.

Evidence, people and systems—never generic technology theatre.
01Human context
Show people focused on real work. Natural light, honest environments, no staged celebration.
02Purposeful detail
Use close crops of materials, interfaces and decisions to make complexity tangible.
03Connected systems
Use grids, paths and evidence labels with restraint. No neon brains, robots or sparkles.

Iconography
1.5 px outline, round joins, 24 px base grid. Icons clarify actions; they never decorate headings.
Data visualizationUse neutral structure and one signal color.
07 · Voice & tone
Clear enough to understand. Specific enough to act on.
Calm
State urgency without urgency theatre. Confidence is quiet.
Specific
Name the source, time, impact and owner. Evidence beats adjectives.
Human
Use familiar words, active voice and respectful guidance.
Responsible
Technology recommends. People remain informed and in control.
