Why everything looks the same
Design systems, component libraries, and template marketplaces made competent design cheap and available, which raised the floor and flattened the ceiling. The result is entire categories of company that are visually interchangeable, and interchangeable brands compete only on price.
Distinctiveness is a memory strategy
The commercial argument for a distinctive system is recall, not taste. A buyer who is not ready today needs to recognise you in three months. Assets that do that work — a colour, a typeface, a structural device, a tone — are more valuable than assets that merely look current.
Pick one device and commit
Distinctiveness rarely comes from many unusual choices; it comes from one, applied without exception. A single accent colour used only for the thing that matters, or one structural rule followed everywhere, reads as deliberate. Five unusual choices read as noise.
Distinctive is one strong decision repeated, not five interesting ones combined.
Constraints make it survivable
A system with two typefaces, three colours, and one spacing rule can be applied consistently by people who weren’t in the original conversation. A system with fourteen approved colours degrades into whatever each person liked, which is how brands lose coherence within a year of launch.
Distinctive is not the same as difficult
Strong visual identity has to survive contact with accessibility and performance requirements: contrast that passes, type that reads at small sizes, motion that respects a reduced-motion preference, and no dependency on assets that make the page slow.
Where a device fails those tests, it is not bold — it is a defect with a rationale. The interesting work is finding the version that is both.
Write down the rules that must not break
Every system needs a short list of non-negotiables: the things that, if changed, mean it is no longer the brand. Keep it to a handful, make it explicit, and put it where the people editing the site will actually see it — in the repository, not in a PDF nobody opens.
