Yikes! Wonder how (ok, why...) they did this. I've seen fridges and dishwashers repainted (and I am guilty on both counts) but not stoves. Is it even safe to apply paint over the original finish? Unless of course they had the whole unit re-porcelained....
It only looks strange in Avocado because we don't expect to see it in such a color.
If they didn't abrade the porcelain enamel before painting it, and the finish wasn't damaged before, it shouldn't be too much trouble getting it back to the original color.
