Route4Green
Design system route4green-pilot · v1.0.0 · published 25/09/2026
Foundation
The brand's rules - philosophy, color and type tokens, usage guidelines - defined once on the design system.
Route4Green is for people who verify before they believe: it exists to show the fleet-level assignment it made and the numbers that prove it, not to describe optimization in adjectives.
The system is FOR dense, scannable evidence - tables, deltas, JSON, schematic route geometry - on light surfaces where reading happens all day.
It takes the stance that a working green and a measured sentence outperform a gradient and a claim; if a screen can't be verified against a dispatcher's own records, it doesn't belong in the product.

Avoid
Stock-smile business photography, aspirational lifestyle logistics scenes, leaf/globe/earth/seedling/eco iconography, decorative abstract shapes unconnected to route geometry, gradients.
Subjects
Real Vietnamese logistics operators mid-task: dispatch room screens and order boards, port loading/unloading, national highway driving from a driver's or roadside perspective, cold-chain warehouse operations, vehicle-level stop scanning and load-checking.
Treatment
Documentary, unstaged-looking, natural light, slightly desaturated to sit quietly behind or beside data rather than compete with it. Crops favor task and hands-on-work over posed faces.
Schematic Role
Polylines, ordered stop markers, before/after route paths and coordinate grids serve as the system's secondary illustration language, rendered in the product's own token colors (green + neutrals + severity hues where relevant) to double as brand mark and technical demonstration.

Traits
Structure
Number first, then how it was measured, then what it means. Never lead with an adjective or an outcome promise.
Language Rule
All Vietnamese copy carries full diacritics; English copy is a high-quality full translation, not a stripped-down summary, for international buyers who don't read Vietnamese fluently.
Color
Green (primary/secondary/accent tints of the single hue) is reserved for brand chrome, links, and primary interactive states (buttons, active nav, focus rings). It must never double as a severity 'pass' color in the same view where brand green also appears as decoration, to avoid ambiguity. Severity reds/ambers/blues live outside the harmony as fixed functional tokens. Neutrals (graphite text, mid gray, paper/card surfaces, data-row tint) carry all table and document density; color is added only where it means something.
Layout
Tables (endpoints, plan results, stop sequences, before/after deltas) use alternating row tints (Data Row Tint), clear dividers, and generous column padding; they are treated as primary content, not secondary detail. Marketing pages lead with a real or realistic API request/response or fleet-split diagram before any descriptive copy block. Fleet-level assignment visuals must show multiple vehicles and redistributed orders - never a single truck's reordered stop list - to keep the core differentiator visually unambiguous.
Dark Mode
Dark tokens live only under a.dark class scope, tuned for extended dashboard/docs reading sessions by engineers, not treated as the brand's face.
Typography
Headings use a confident, slightly technical sans for wordmark/lockup harmony with the kept 'R' mark; body uses a highly legible workhorse sans at 16px/1.5-1.75 for long documentation reads. Monospace is reserved strictly for code, JSON, endpoint paths and coordinate data at 12-14px/1.2-1.4 line-height, always visually distinct from body.
Identity
How the brand looks in practice - logos, imagery and artwork produced by its current design.
