Good question; my idea is that on snow-covered airports, which traffic on the ground, normally you cannot really see the end of the wings (they blend in with the snow), so to provide clearance with other traffic they are painted red. So it makes them more visible. I am not sure if this is true, but just my idea about it!
What IS true is that former Aeroflot aircraft operating in the Arctic and snow covered regions had red colours and red wing surfaces to make them more visible in the white environment, thats why I believe they painted the wingtips red too
