What the assessment must establish

To assess design changes in the Shell logo, compare authorised vector artwork of the current pecten—the company’s scallop-shell emblem—with the previous authorised artwork, and record what differs in outline, internal geometry, colour fields and any wordmark lockup. That record is what tells you whether existing templates, signage files and print-ready art remain valid. Screenshots, photographs of signs and flattened raster exports hide the path structure you need to judge, so they are supporting references only.

A vector logo is artwork defined by paths: sequences of anchor points connected by straight segments or Bézier curves, the mathematical curves that describe smooth outlines. Fills and, where used, strokes are applied to those paths. Assessing a logo change means inspecting those paths and fills, not inspecting a picture of the logo.

A lockup is a fixed arrangement of the emblem with a wordmark or other elements. If the current mark is issued as an emblem-only file and as one or more lockups, treat each file as a separate artwork to compare.

What to inspect in the artwork

Work from files issued as brand artwork, not from reconstructed drawings, unless the task is explicitly to rebuild. Open the current and previous files in a vector editor and inspect the points below. Record what is in the files; treat values in a brand manual as documented requirements only when you have that manual.

  • Silhouette of the pecten: outer contour, number and shape of ridges, and whether the left and right sides match.
  • Internal colour split: how the two filled fields of the pecten are divided—in the familiar mark, a red upper shell and a yellow lower shell—and whether they are separate closed paths, a compound path (multiple outlines treated as one fill), or overlapping shapes. Official colour systems are documented only when a brand manual supplies them.
  • Outline treatment: a true stroke, an expanded outline (a stroke converted to a filled shape), or no outline.
  • Anchor and curve quality: extra anchors, broken symmetry, or flattened curves that will show at large sizes.
  • Wordmark, if present: letterforms, spacing and alignment relative to the emblem. Stretching or redrawing old lettering by eye is not an update.
  • Colour specification stored in the file: named spot colours, process (CMYK) builds, or RGB values.
  • Construction hygiene: stray points, hidden layers, embedded raster images and clipping masks that fail in cut, print or SVG use.

Why those changes matter

The pecten is a simple, high-contrast emblem, so a small geometric edit reads as a new mark once the logo is reproduced at scale. A change in ridge count or in the curve of the outer shell alters cut paths, embroidery stitch maps and vinyl weeding. A change in how the two colour fields meet—butt join, overlap, or a gap—changes trapping and the risk of a white hairline on press or on screen.

Outline weight and optical adjustments, meaning subtle thickening or rounding so the mark still reads at small sizes, affect minimum reproduction size. If the current artwork includes a redrawn wordmark, every lockup that still uses the old lettering is obsolete. These are reasons to compare the files as paths. They are not, by themselves, proof of a particular redesign date or designer.

Visual judgements such as flatter, more geometric, or friendlier are interpretation. They can help describe a difference you have already measured in the paths. They do not substitute for stated design intentions in attributable brand records.

What this brief cannot confirm

Dates of each Shell identity refresh, the designer of record, and any official statement of why the mark was changed are not supplied here. Take those points only from attributable brand or design-history records. Do not infer them from a filename, a headline, or the look of a single file.

A file extension such as .ai, .eps, .pdf or .svg is not proof that the content is vector-only, that paths remain editable, or that you have permission to reuse the logo. Licensing and artwork approval sit with the brand owner. Documented requirements in a brand manual—clear space, minimum size, colour systems—override informal design recommendations.

When the comparison is finished, you should be able to state in writing which authorised files you compared; which geometric, colour and lockup differences you found; whether those differences require replacing existing deliveries; and which facts remain unverified, including chronology, authorship, licence and official colour. That statement is the decision record for sourcing, drawing or handing off the artwork.
