There are in fact several food dyes in the EU that are "banned" in the US.
Using the word "banned" though is misleading. Most things are not approved because no one has petitioned for approval, not because they were found harmful. This happens more in Europe than the US though because the US has GRAS.
This, exactly.
And to clarify, since it appears to not be well known even in the US, that GRAS = Generally Recognized As Safe[0], which isn't necessarily all that safe given the "testing" required to meet that "standard."
