No silver paint - polished alu. They came that way - altho' the blue would originally have been green.
It's a really nice bike. Clocked up >1000 miles on it since September. Dirt cheap - except its "good" wheels. And the lightest 1-gear I've had except for a custom built Langster. I don't normally like alu forks, but these are fine (don't know if being 1 1/4" rather than 1 or 1 1/8 helps).
