The nucleus that connects and orchestrates a system.
CORE is not a circle. It is not a stylized O. It is not a dot with decoration around it. It is a dominant nucleus holding a subordinate system — the same reading its geometry, brand architecture and visual language repeat in every application.
Concept
CORE is the nucleus that connects and orchestrates a system. The outer ring dominates because it is identity; the inner ring is subordinate because it is relation, connection, circulation — it never competes with the nucleus, it accompanies it.
"CORE is a circle." — loses the nucleus/orbit hierarchy.
"CORE is a stylized O." — reduces it to a variation of ODDY.
"CORE is a dot with decoration." — inverts the weight: the nucleus stops dominating.
Symbol D3-C — CORE Symbol Master
Master asset. Every later application in this document derives from this single source — it is never redrawn by hand.
| Asset name | CORE SYMBOL MASTER |
| Variant | D3-C · N0/R0 |
| Concept | dominant nucleus + inner orbit |
| Status | frozen — 41/50 in comparative validation |
| Geometric origin | ODDY's ring DNA, reinterpreted |
Construction
Technical specification faithful to the master. Reproduce these exact values — do not eyeball it.

| Inner cut | rx 64 · ry 34 |
| Cut offset | +6 / -4 from center |
| Resulting thickness | 22 / 18 (≈25% of radius) |
| Inner orbit | |
|---|---|
| Outer radius | rx 50 · ry 27 |
| Inner cut | rx 44 · ry 22 |
| Cut offset | +2 / -1 from center |
| Gap from nucleus | 14 / 7 |
| Reference box | viewBox 200 × 200, center 100,100 |
| Incline | -20°, applied equally to both layers |
| Test color in this document | #152238 — see § 06 Palette |
Clear space
A unit derived from the symbol itself — never an arbitrary pixel value.
X = total symbol height ÷ 4.
No foreign element (text, container border, another logo) may invade a margin smaller than 1X around the symbol. The CORE wordmark and the CORE Group lockup inherit the same X unit, calculated on the symbol's height within each lockup — not on the full composition.
Minimum sizes
Three distinct criteria — not interchangeable.
| Element | Minimum digital | Minimum print | Minimum comfortable |
|---|---|---|---|
| Isolated symbol | 16 px | 6 mm | 24 px / 10 mm |
| CORE wordmark | 24 px height | 8 mm height | 32 px / 12 mm |
| CORE Group | 28 px height | 10 mm height | 36 px / 14 mm |
Palette
Color was defined by what it needed to communicate, not the other way around. CORE needed real distance from ODDY — not just a different hue, a different register: where ODDY is vivid, luminous blue (operating brand, energy), CORE is a deep, almost graphite blue (platform, system, institutional sobriety). Same chromatic lineage, opposite roles.
Neutrals
Semantic
Typography
IBM Plex — one super-family covering display, text, UI and data without fragmenting the system.
Wordmark
The symbol never competes with the word. Primary configuration: horizontal, symbol on the left.
Primary — horizontal, symbol + word
Secondary — stacked, for square formats
Isolated symbol — favicon, avatar, app icon
CORE Group
Superior corporate expression. Not a different company — the same symbol with a smaller second line of hierarchy.
"Group" never exceeds 40% of "CORE"'s size and never competes in visual weight — it is corporate structure endorsement, not a second brand name.
Brand architecture
Four levels. Each answers a different question.
Operational model: who does what
This relationship is functional, not a second brand hierarchy — it does not replace the four levels above.
Charlie defines. CORE orchestrates and executes. ODDY operates territory logistics and is the parent of OnDemand, which operates free-trade-zone and international logistics. COMITA trades goods; FACILIA delivers services. ODDY is never a parent of CORE.
Relationship with ODDY
Three ways of coexisting, resolved by hierarchy, space and typography — never by graphic fusion. ODDY is represented here only as a position reference: the official brand file must replace this placeholder in production.
Both as equivalent corporate units. Use: institutional footer, joint presentation closing, B2B materials between peers.
CORE dominates, ODDY backs it in smaller type. Use: product, login, dashboard — where the user interacts with CORE.
CORE Group as the umbrella, ODDY listed as an operating unit. Use: manual, org chart, institutional documentation.
ODDY's logotype, symbol, construction, proportions, colors and typography are not modified, redesigned, reinterpreted or fused with CORE anywhere in this document. Every "ODDY" element shown above is a position placeholder — not a brand reproduction.
CORE Orbit
The Orbit guide is an institutional communication tool — covers, presentations, motion. The D3-C symbol (§ 02) works complete without it. They are never combined into a single logo asset.
Reduction system
No technical adaptation is necessary — the master was already validated at 16px in the prior micro-test round. Same geometry, no exception, across all five scales.
Favicon
16px, geometry identical to the master.
App icon
32px and above. The symbol works with generous margin — it does not need a color background to hold up.
Versions
Positive, negative, monochrome. D3-C geometry with no exception across the three.
Incorrect uses
Illustrated only to document the error — none of these examples is a valid variant.
Do not modify ODDY to solve any problem in this section. If CORE clashes with ODDY in an application, the fix happens on CORE's side and in the composition — never on ODDY's asset.
UI color system
Products consume tokens, not loose hex values. All of them derive from the CORE architecture — there are no isolated per-application palettes.
| Token | Value | Role |
|---|---|---|
| CORE Primary | #152238 | Brand, symbol, text on light |
| CORE Accent | #0E8A82 | Interaction, focus, CTA |
| CORE Background | #F5F6F8 | General product background |
| CORE Surface | #FFFFFF | Cards, panels |
| CORE Border | #E2E5EA | Dividers, outlines |
| CORE Text | #101423 | Primary text |
| CORE Muted | #5B6273 | Secondary text, placeholders |
| Success | #1F9D63 | Confirmations |
| Warning | #C98A1B | Attention |
| Error | #D64545 | Blocked, failed |
| Info | #2E7FD6 | Neutral informational states |
Active shipments
Verticals
Extensions of the CORE system, not independent brands: same symbol, same wordmark, one identifying tint per vertical, always in the same saturation/lightness band.

Master rules — summary
This document stands as the base for CORE Brand Guidelines v1.0 and the starting point for real production: SVG/PNG export of the master symbol, favicon and app icon generation, UI components on the tokens defined in § 18, and corporate pieces on the lockups in § 08–09.
