A formulator in Ohio writes ‘color’. A buyer in Manchester writes ‘colour’. Both are chasing the same beet extract, yet their spec sheets, labels and even legal categories can differ. It sounds like a spelling quirk, and it is far more than that. If you sell across borders, knowing how natural food colors are described in each region saves rewrites, delays and confused customer emails.

More Than a Spelling Habit

American English drops the u and British English keeps it, so documents from different regions naturally mirror that split. The trouble starts when the vocabulary around the ingredient changes along with the letters. Mixing the two up in a document set is an easy way to confuse a customer.

A supplier selling into both markets may keep two versions of a specification, each using local terms for the same material. Compare them line by line before assuming they describe different products.

How British and European Documents Read

In Europe, many pigments are authorized additives with E-numbers, such as E162 for beetroot red or E100 for curcumin. Documents often print that number beside the common name, and buyers there expect to see it. A buyer comparing two suppliers will often trust the one that quotes the code correctly.

Customers searching for natural food colours in the UK usually want that regulatory detail together with the ingredient name. A page or sheet that carries both answers the question faster than one that carries only a name.

The US Approach in Brief

In the United States, color additives from plant sources are generally listed as exempt from certification. On a label, they often appear by name, for example annatto extract or beet juice color, rather than by number.

That naming habit shapes how American buyers describe what they want. They tend to ask for a source, such as turmeric or paprika, before they ask for any code. A source name also tells a formulator what to expect in terms of stability.

Colouring Foods, a Separate Idea

European guidance treats some fruit and vegetable concentrates with colouring properties as foods in their own right, not additives. Carrot concentrate made this way is declared by its ingredient name, without an E-number. It is a subtle distinction, and it surprises many first-time exporters.

The line depends on how the material is made. Selective extraction that isolates the pigment usually pushes it back into the additive category, so confirm classification with a regulatory adviser for each market.

What This Means for Product Pages

Use both spellings naturally in descriptions and headings. People type what feels familiar, and search engines treat the variants as related but not identical. Sentences that work in one dialect often feel slightly off in the other.

Avoid forcing both into one sentence. Separate regional sections read more cleanly and let you attach the right regulatory notes to the right audience.

Working With Suppliers Across Regions

Ask which documents a supplier can issue for each market: specification sheets, allergen statements and regional compliance letters. A supplier used to exporting will have them ready without much chasing. Saving those documents under clear regional names avoids confusion later.

Check that numbers match across documents. A purity or strength figure that differs between the UK and US versions of the same sheet deserves a polite question.

Common Slip-Ups

Typical errors include copying an E-number onto American artwork, calling an additive a colouring food on a UK pack, or translating regulatory phrases word for word into another language.

A short internal glossary, kept by the regulatory lead and shared with marketing, prevents most of these mistakes before artwork reaches the printer. It costs an afternoon to write and saves weeks of corrections.

A Simple Glossary to Keep

List each ingredient with its US name, UK name, any E-number and the usual declaration wording. One page is enough, and updating it takes minutes when a market changes its rules. Small edits are easier than rewriting everything at once.

Revisit it yearly. Regulations move slowly, but they do move, and a stale glossary gives people confidence in answers that are no longer correct.

Bottom Line

Spelling is the visible difference, but the real gap sits in classification, naming and documentation. Teams that map those differences early spend far less time fixing packs after the fact. That mapping pays off every time a new market opens.
