Maybe it's just me but a lot of recent posts are getting really hard to understand. No offense but your post is pretty crazy sounding. Then again, mine aren't so great either.

This is what I'm guessing you're saying:
You just purchased a civic that has a pearl white paint job with orange flake. It used to be red and you can see the old red paint in the door jambs and under the trunk and hood. So now you're wondering if you should try painting those sections white?

Here's my answer:
I don't think it will look good but if it bothers you enough, go for it. It won't match but there will be less contrast. Otherwise, I'd save myself the hassle and just leave it as is if it's not that bad.
