If its in a basement you don’t need anything as hardwearing as garage paint, -the point of it is to not bind with car tyres when they’re left parked on it for long periods – thats not a situation thats going to occur in your cellar so don’t pay extra for it. Garage paint has a really, really slick surface which can be a bit of a pain as things you what to stay still can skate around the room a bit, then if you want to push anything heavy round you can’t get any traction.
Bog standard floor paint will be fine – you should be able to get a fairly pale grey (or sometimes a pale buff / sandstone colour) keep the colour as pale as you can and it will bounce light around and help with illumination if you don’t have any natural light.
