Custom Zippo engraving ideas?

I have a few questions regarding this.

What is the cost for engraving?
Is it possible to engrave a colored Zippo, and if so, what is the visual result?
Does the color on these Zippos peel, or is it permanent? For instance, would a red one lose its finish over time?

Those are my inquiries. To be clear, we are discussing genuine Zippo products, not knockoffs. 😁

It’s been about ten years since I did this—man, where does the time go? 😲—but I ordered a $15 if my memory serves me right. It had this little logo on one side and a short inscription on the other.
I picked it up back in Prague at this tiny boutique... I can't for the life of me remember the name 😬
.
Now that you're asking about a colored Zippo... honestly, I have no idea how that would even turn out. 🤷
