Filter question

[T&E Run]

I've been watching some of Bryan Peterson's videos. One that I like is "taking pictures after sunset". He's shooting a cityscape 20 minutes after sunset. He suggest using a FLW Magenta filter. Can this same effect be done in RAW editing software (without using that filter) by adjusting the white balance, or other? Thanks.

I've always wondered why they say this about magenta filters, why do people insist on using them at night?

We used to use gels to add "romance" to our car shots for ad agencies. Regarding WB generally, reality isn't everything. Would we try to make a sunset neutral? The "Correct" WB may not be the "Right" WB for a image. Remember, you're the judge of your own image.
For example, the color of this P-51 is all "wrong", isn't it?
