Logo review meetings tend to run on preference. Someone dislikes the blue. Someone else wants it "bolder." None of this predicts whether the mark will still be working in five years.
The properties that do predict it are testable.
1. It survives at 16 pixels
Your logo will spend most of its life as a favicon, an app icon and a social avatar — a small square, often on an unfamiliar background. A mark with fine linework, a gradient or four words in it turns to mush at that size.
The test: export at 16×16 and 32×32. If it is unrecognisable, you need a simplified secondary mark. Most strong identities have one.
2. It works in one colour
Embroidery, engraving, single-colour print, a fax from a supplier in 2003. If the design collapses without its gradient, it is an illustration, not a logo.
The test: flatten to pure black on white, then pure white on black. Both should read cleanly. If the white version fills in, your counters are too tight.
3. It is distinctive within its own category
Every industry has a visual cliché — the swoosh for logistics, the leaf for wellness, the abstract cube for technology, the blue shield for security. These persist because they communicate quickly. They also make you invisible.
The test: put your mark on a slide with eight competitors' logos, greyscale, no names. Ask someone unfamiliar with the category to find yours after five seconds. If they cannot, it is not a mark — it is category wallpaper.
4. It reproduces cleanly at scale
Vehicle livery, a trade-show banner, a building sign. Blown up, weak curves and inconsistent stroke weights become obvious. Anything raster becomes unusable.
The test: view the vector at 2000% and look at the curve joins.
5. It describes the business, not the product
A literal illustration of what you sell today is a constraint on what you can sell tomorrow. A house in the mark is a problem when you expand into commercial property. A camera is awkward once you are a software company.
The strongest marks are frequently abstract or typographic precisely because they carry meaning rather than depict it.
6. It has a system behind it
A logo delivered as a single file is an unfinished job. A usable identity includes:
- Primary, secondary and simplified marks
- Horizontal and stacked lock-ups
- Clear-space rules and a minimum size
- Full colour, single colour, and reversed variants
- Vector plus web-optimised raster exports
- A defined palette with hex, RGB, CMYK and Pantone values
- The typefaces that accompany it, and their licences
Without this, every future application becomes an improvisation, and the identity drifts within a year.
7. Someone can describe it out loud
If a person can say "it's the one with the folded arrow," you have a mark. If the best they manage is "it's a blue sort of shape," you have decoration. Verbal describability is a decent proxy for memorability.
What none of this covers
Whether it is beautiful. That matters — but it is the last 10%, and it is the only part everyone in the meeting feels qualified to discuss. Run the seven checks first. Argue about the blue afterwards, once you know the mark can actually do its job.
