Alloys (preferably black) for winter tyres

My Octy Estate 4x4 is due end October & comes with the standard 16" (205/55 R16 91V)Ilias alloy wheels. I'll be doing at least two winter alpine trips a year so I'm planning on putting on a replacement set of 16" wheels/winter tyres which I'll leave on all winter.

Have seen plenty of steel rim options but for aesthetics I'm thinking of a set of 16" alloys, preferably black as the car is Corrida Red with black roof bars. Any recommendations for sensible priced wheels that won't fall foul of any 'modification' issues with my insurance company?
