Implicating light_blue_fur → blue_fur
Link to implication

Reason:

I think this is overly specific, but since this tag exists, having an implication to "blue fur" is logic.

I'd rather alias the two. Tagging different shades of the same colour seems a bit overly specific. Also, as far as I know, the beige_fur tag was removed for similar reasons. (see forum #83071)

I agree with EsalRider, an alias would be better.

Agreed, will alias if no one disagrees

An alias looks fine to me.

Agreed on alias.
