If observing starlight through instruments sensitive only to narrow bands, what might be isolated from a massive star that is otherwise perceived as blue?

Answer

A violet component

While the overall visual appearance is dominated by blue/UV for hot stars, specialized instruments might isolate a violet component if its underlying emission profile exists, though the star's classification remains based on its peak blue/UV output.
