The Dyeu design system.

One petrol monochrome palette, one type system, and a signature hairline motif. This is how Dyeu looks, and how to use it.

Logo

The wordmark and the mark.

The wordmark is the primary logo. The mark, the D on a petrol tile, is for square contexts like favicons and app icons. Give both clear space of at least the height of the D on every side.

Color

Petrol on a tinted monochrome.

Near-white and near-black tinted toward petrol, with one restrained petrol accent used only where something is interactive or active.

Geist Mono · labels and data

By the numbers

Motif

Hairlines that carry meaning.

The signature is a field of ultra-thin lines and a vertical fluted-glass panel. The same vocabulary encodes different functions across the product.

Motif · applications

One motif, eight jobs.

Every variant keeps the same vocabulary, thin strokes with petrol only where it means something, but each encodes a different function. Presence reacts to the cursor; the rest animate on their own.

Reactive

Presence

Heroes, empty states, and the moment the agent is listening.

Data

Signal

Metrics, digests, and status at a glance.

Process

Working

Loading, a running task, and a streaming reply.

Static

Structure

Decks, documents, and dense dashboards.

Live

Pulse

Background monitoring, scheduled runs, an idle agent still awake.

Connection

Flow

Connected tools, integrations, and routing.

Threshold

Alert

Anomalies, thresholds, and things that need a look.

Attention

Focus

A primary call to action, an onboarding step, or notice this.

Motif · patterns

Backgrounds and dividers from the same hairlines.

A fine dot grid, fine vertical lines, and a vertical hairline ruler with light streaks passing through it. Used for section breaks, quiet page texture, and ad backdrops.

Voice

Sharp, considered, human.

No emoji, ever

The agent never uses emoji. Warmth comes from the words, not decoration.

No em dashes

Sentences use commas, colons, or periods. Clean punctuation, nothing ornamental.

Considered over eager

Notice the non-obvious and lead with the useful thing, thoughtful rather than eager to please.

Human, not a chatbot

Write like a sharp colleague. Direct, no filler, no hype, no chatbot tells.
