Why is titanium dioxide with dyes?
Households that filter artificial colors usually want the white pigment in that same bucket. You can still allow-list this one ingredient if you want the other dyes without it.
Artificial dyes
Titanium dioxide
A white pigment printed as titanium dioxide, E171, or CI 77891.
Matches personal ingredient preferences based on label evidence; not medical, allergy, or dietary safety advice
What the label is naming
Titanium dioxide is a white color additive. Food labels may spell the name or use E171 or CI 77891. The catalog files it with dyes because shoppers who avoid artificial colors usually list it there. The match is the printed name, not a brightness judgment about the food.
Where it hides
White coatings on candy, some coffee creamers, powdered sugar decorations, and dressing bases that want a brighter appearance. It is easy to miss at the end of a long list.

Questions
Is E171 always titanium dioxide on a food label?
In food-additive numbering, E171 refers to titanium dioxide, so the catalog treats that code as this ingredient.
