The problem is not small birds, it is big birds like eagles that can get 20 years old. For example in northern Germany wind turbines are the most common factor of death for them. Thus if just one blade needs to have a different color ot prevent collision and death then it is a pretty decent solution for a major problem.

That solves (or reduces) one (debatable) problem, but increases another (also debatable) one: anyone who considers wind turbines an eyesore and doesn't want to have them anywhere near will be even more likely to do that if their visibility is increased like proposed here...

I thought about this too, but I'm not sure there is anything you can do to make this group happy, short of removing the turbines. So is it worth even considering their perspective? I know that's a harsh question.

Do you have a source for that? Eagles may not be prey for cats, but they still encounter buildings and masts, from the list in another comment.

But how many rabbits and squirrels are saved by the lack of eagles?

Is that supposed to be an actual argument?
