How to read Cranfield Colours's ethics scores
Each Cranfield Colours product on this page carries a 0–100 score built from four checkable inputs: active third-party certifications, disclosed ingredients or materials, published supply-chain information, and the brand's watchdog record. Nothing here is based on Cranfield Colours's own marketing language.
The spread matters as much as the top score. If Cranfield Colours's highest and lowest products sit far apart, verification is being applied to some lines and not others — common when a company certifies a flagship range and leaves the rest undocumented. A narrow spread, even at a moderate average, usually signals a consistent policy.
Scores can move without any editorial change, because certification status is re-checked as pages refresh. A lapsed certificate, a new audit or a recall notice will all show up in the product's certification and notes sections.
Questions worth asking before buying Cranfield Colours
Start with ownership: a parent company's testing or sourcing policy can change what a claim on the packaging actually covers. Then check scope — a certification often applies to one fibre, facility or ingredient rather than the whole product.
Finally, compare within the category rather than against Cranfield Colours's own range. A mid-scoring product can still be the strongest verified option at its price, and a high-scoring one can be beaten by a cheaper certified alternative.
What each score input covers
| Input | What we check | Why it matters |
|---|---|---|
| Certifications | Active listings in public registers, with scope and expiry | Only externally audited claims can be revoked |
| Ingredients & materials | Full disclosure, hazard flags, recycled or organic content | Comparable without trusting brand narrative |
| Transparency | Named suppliers, factories or audit summaries | Shows whether claims survive scrutiny |
| Record | Recalls, regulator rulings and greenwashing findings | Best short-term signal of quality control |

Frequently asked
Is Cranfield Colours an ethical brand?+
Cranfield Colours's standing here is the average of its scored products, built only from verifiable inputs: active certifications, disclosed ingredients or materials, published supply-chain data and its recall or regulator record. Where a claim cannot be checked in a public register, it earns nothing.
Is Cranfield Colours certified by third parties?+
Any certification we could confirm appears on the individual product cards above. Marks shown are matched to the certifier's own register; self-declared logos and internal awards are not counted.
Why do Cranfield Colours products have different scores?+
Scores are per product, not per brand. Differences usually come from certification scope, ingredient or material disclosure, and packaging — a certified flagship can sit far above an undocumented line from the same company.
Are there better alternatives to Cranfield Colours?+
Compare within the category rather than the brand: category rankings list the highest-scoring verified options at each price level, so you can see whether a cheaper certified alternative beats the Cranfield Colours product you were considering.
