Digital Norse
Logo, color, type, voice. How Berserk looks and sounds.
Logo
The mark is a raven — drawn from the Hrafnsmerki, the Raven Banner that Scandinavian lords carried into battle and which is arguably Denmark's first flag. The raven is also Huginn and Muninn, Odin's birds, flown across the worlds to report back what they saw. It's drawn as a single brushed silhouette, paired with the Parkinsans wordmark in the lockup. Both sit in Berserk Green on dark, or in dark on Berserk Green. Never inverted, never multicolored, never drop-shadowed.
Primary lockup — horizontal
Stacked lockup
Use the horizontal lockup for headers, footers, and any wide field. The stacked lockup is for square or portrait spaces — social avatars, app icons, badges. The mark also travels on its own.
Mark — on dark
Mark — on accent
Clear space
Leave a margin equal to the mark's sail height on every side. The logo never crowds neighbouring elements.
Rules
- Minimum 24px on screen, 6mm in print.
- Do not rotate, skew, or recolor the mark.
- Do not place the green mark on backgrounds between #1A1A1A–#3A3A3A — contrast drops below comfortable.
- Wordmark is set in Parkinsans Regular, uppercase, tracked +0.15em. The display lockup uses a heavier drawn weight; the running wordmark stays light.
- The mark and the word "Berserk" can travel separately; the inverse is fine too. Don't invent new lockups.
Colors
A single accent does the heavy lifting. Everything else is the dark canvas, white text, and quiet supporting greys. Restraint is the point — the brand is loud enough in name; the surface should be calm.
Berserk Green
Primary mark. The single accent color across the surface.
Background
Page canvas. Near-black, never pure black.
Foreground
Body text and titles on dark.
Muted
Supporting copy, captions, secondary navigation.
Border
Card outlines, dividers, rules.
Wave Teal
Resting ocean glyphs. Appears in the hero rune-field.
Typography
Three typefaces, each with a clear job. The wordmark stands alone; everything else stays out of its way.
Wordmark — Parkinsans Regular
BERSERK
Uppercase, tracked +0.15em. Used for the wordmark and any running text that wants the lockup voice.
UI & body — Geist
We finally fixed observability.
System sans for everything that isn't the wordmark or code.
Code & data — Geist Mono
union otel_logs, otel_traces | trace-find { search "500" }
KQL, command output, anything where alignment matters. Colours match the product editor.
Text is our medium
LLMs have pulled the centre of gravity back to the terminal: agents read and write text, the most expressive interface we have is a prompt, and ops work happens in the same shell it did thirty years ago. Berserk is built for that world, and the brand says so before you read a word of copy.
Old Norse wasn't only the language of raiders; it was the language of skalds, navigators, and shipwrights — people who paid careful attention to the world and wrote it down. That's the part we kept, applied to a very new world: telemetry.
Use Elder Futhark sparingly, and only to stand in for encoded or otherwise unreadable data — the role The Matrix gave katakana.

Motion is dithered and slightly low-fi on purpose. It evokes a CRT, an old serial console, the moment a phosphor cell decays — the texture that lets the surface stay dark and quiet without feeling sterile.
The colour fringing across the brand surface is chromatic aberration— the same effect a real phosphor display produces when red, green, and blue beams don't perfectly converge. We use it to wake CRT nostalgia on purpose.
Always purposeful
Animation reveals a thing. We don't animate to add motion; we animate to say something.
Low-frequency, high-precision
Ten frames per second where character matters, sixty where field motion does. Sparse, accurate, never frenetic.
Dithered, not smoothed
We accept the pixel. Anti-aliasing belongs in product UI; in the brand surface, the rough edge is the texture.
The world emerges, the world recedes
Things fade in over 400ms, hold 3s, fade out over 1s. Show, hold, dissolve — that's the heartbeat.
Voice & Tone
Berserk is loud as a word; the brand is mostly the opposite — precise, friendly, a little deadpan.
Disarming by default, sharp when it earns it
A wink, not a war chant.
Do
We named it Berserk because it scans hard and asks nothing of you up front. Throw all the data you want at it.
Don't
Unleash the fury. Crush the competition. Dominate observability.
Plain, not jargony
The audience is engineers. They can tell when a sentence is hiding behind itself.
Do
Logs, traces, and metrics on one engine, stored on object storage, queried in KQL.
Don't
Hyper-converged, AI-native, next-generation telemetry mesh leveraging the modern data stack.
Curious first, combative rarely
Most of what we write is an invitation to look. We can land a sharper line when the story calls for it — but it stays one line, never a paragraph, and never as the default voice.
Do
Ask one question across logs and spans, get the answer, move on.
Don't
Smash the silos. Destroy the dashboard. War on telemetry sprawl.
Assets
