Personally, style comes first since that's what everyone will see when it comes to your car, it's also your first step to customizing your vehicle. Colour would be a close second and then price. I've never paid much attention to weight in the past, mainly because the lighter wheels are usually more expensive.
Lightweight wheels give you a lower overall weight giving you better fuel economy and (I believe) better handling.
