yellow 6

Color additive

Yellow 6 is a synthetic azo dye with no nutritional role in pet food. Why it is there, and how Bowlmark scores artificial colors.

Also appears on labels as: yellow no. 6 · fd&c yellow no. 6 · fd&c yellow 6 · sunset yellow fcf · e110

What it is

Yellow 6 — sunset yellow FCF, or FD&C Yellow No. 6 — is a synthetic azo dye closely related to Yellow 5. Like every color additive, it has no nutritional function; its entire job is to change how the food looks.

Why it's in pet food

Color is for the shopper: dyes make kibble pieces read as golden, meaty, or varied on the shelf. Advocacy and regulatory reviews keep synthetic dyes under scrutiny, and there is no nutritional upside to offset the questions.

How Bowlmark scores it

Scores are deterministic math over the printed label — the rules below apply to every product identically, and nothing estimates or fills in a blank.

The additive pillar deducts 12 points per distinct artificial dye on the label — Yellow 5, Yellow 6, Red 40, Red 3, Blue 1, and Blue 2 — capped at 36 points, each shown as a warning flag.
