How long have you had it? Looks difficult to repair, if a powder coat that's an engine strip down, but why is it flaking off? Is it high mileage and old or young and factory hasn't prepared it properly and under warranty?
Collor engine
Long story short:
send a mail to Honda and they said go to your dealer.
dealer said we don’t have the color, we need to send the part to a painter and they make the color
friend of mine is painter but the device is to big to scan the color
many advise would be appreciate
