color variant Fix “Colour inconsistency across variants” on Meta Commerce Manager
Variants under one item_group_id have inconsistent colour formatting. Some say 'Navy', some 'NAVY', some 'navy' — Meta treats each as a different colour, fragmenting the variant group.
What you see in Meta Commerce Manager:
Colour inconsistency across variants Variants under one item_group_id with inconsistent colour casing ("Navy" vs "NAVY" vs "navy") get treated as separate colours. The variant grouping fragments and Meta can't tell the variants are the same colour at different sizes.
The fix is case consistency at feed generation. Title case (Navy, Black, Red) is the safe default. Apply consistently across all variants of an item_group.
Top causes
- 1
Bulk import where casing was inconsistent
- 2
Manual data entry across multiple sessions
- 3
Multi-platform sync where colour fields normalise differently
How to fix it
- 1
Standardise colour casing
Title case (Navy, Black, Red) is the safe default. Apply consistently across all variants of an item_group.

Audit your full catalog for casing inconsistencies
Quick check: group by colour, look for casing variants. Usually a few obvious offenders.

Invalid colour
The color attribute is populated but with a value Google can't recognise — usually free-text marketing names ('Midnight Whisper', 'Sahara Sunset') that don't map to standard colours. Items still serve but with reduced filter eligibility.

Feed colour doesn't match what the landing page or image shows. Common when 'Midnight Whisper' is in title but the colour field says 'Black' (acceptable) vs. when actual product shown is blue (not acceptable).

FAQ
Does case sensitivity really matter that much?
Yes for variant grouping. 'Navy' and 'navy' are different colours to Meta's classifier.
