Brand assets and PDFs

DEISO's logos, brand identity, color palette, and company profile — for partners, suppliers, media, and public sustainability organizations using DEISO marks in approved communications.

Every file below is the current 2026 brand. Older marks are deprecated and should not be used. Use the preview backgrounds as a guide — each version is built for a specific context: dark, light, transparent, horizontal, stacked, or symbol-only.

Brand identity

The DEISO mark — what it represents

The DEISO symbol is a continuous, layered ring built from overlapping arcs that flow from sage green into teal, with a slate-blue shadow grounding the form. The ring is closed — a system, not a stage diagram — which is how DEISO frames sustainability work: integrated, repeatable, and ready for verification.

What each arc represents

  • Teal (#008194) — the signature brand colour and primary plate. Data, life cycle thinking, and the bridge between environmental substance and technical execution.
  • Sage green (#63976B) — the secondary plate. Natural systems, ecological outcomes, and the environmental substance behind every project DEISO touches.
  • Teal-mid (#2D8B8A) — the transition arc where sage meets teal. The integration point between the natural side and the technical side of a project.
  • Darker teal (#006675) — the deep teal band inside the mark. Engineering rigour, ISO-aligned methodology, and the depth of technical execution behind DEISO’s project work.
  • Slate-blue shadow (#3B5D73) — the operational ground. Documentation, governance, and the traceability layer that lets the work hold up under review.

Wordmark and slogan

The DEISO wordmark is set in a clean, geometric sans intended to read as engineering-grade rather than decorative — quiet confidence, no ornament. Beneath the name sits the slogan “Make Impact” — short, declarative, and pointed at the outcome the company is hired to produce: measurable change, not a report.

The name DEISO

DEISO is an acronym. Both the English source and the Japanese form carry the same meaning:

English Integrated Environmental Sustainability Oriented Research and Development
Japanese 統合的環境サステナビリティ研究開発（デーソ）
Colour palette

Brand colours

Usage guidelines

How to use the DEISO brand

These guidelines keep the brand consistent across every surface where DEISO appears — partner decks, supplier deliverables, certifications, public sustainability reports, and media coverage.

Do
Use the version built for the background — transparent for layouts you control, white or dark for layouts you do not.
Keep at least the height of the DEISO "D" as clear space around the lockup on every side.
Scale proportionally. Use SVG or high-resolution PNG for any surface above 200 pixels wide.
Use the navy-text versions on light backgrounds and the white-text versions on dark backgrounds — never the reverse.
Pair DEISO content with the locked brand colors listed above.
Don't
Recolor the symbol, the wordmark, or the slogan — including single-color or one-tone variations.
Rotate, skew, distort, add drop shadows, outer glows, or 3D effects to the mark.
Reconstruct the wordmark in a different typeface or alter the slogan text.
Use the symbol-only mark in external partner, supplier, or client materials without written authorization.
Place the mark on a background that reduces contrast below readable levels — busy photography, low-contrast gradients, or matching brand colors.
