I agree that it is close to the same color as the steering wheel but lacks the glossiness of the steering wheel.
The aftermarket ones are painted the Champaign interior color which is clearly wrong, even though they do look nice.
I happen to have a very nice steering wheel with 90 % of the original paint, and a very nice original horn button to base these observations on.
