Nothing new comes in paint, due to cars fading over time. It also makes it impossible and very expensive to sell a part to someone with a red car if you only have 15 green and blue ones in stock.
Even dealerships won't stock partss in colour, they'll just offer to paint them at a cost when you buy them.
Wow! You're quite lucky over there!
Here, stuff comes painted to the original paint code. If your car has faded, well tough. (at least, last time I brought new parts for a new-ish car). Would be nice to get them to do that!
That said, some of the people in our parts shops would have trouble adding 1 and 2 consistently, let alone getting you the right part for the right model, let alone doing a decent job of painting it.
