It would more likely to be pollinated by insects. 
This is because the bright color of the petals can attract insects towards the flower thus sticking some pollen grains and transfer them to the stigma (female part of flower). 
On the other hand, the color of petals do not really have effect on the wind pollination. Therefore this explains why wind pollinated flowers usually have small or dull colored petals. 
 
        
             
        
        
        
<span>Atoms that have filled outermost energy levels and do not participate in chemical bonding are called Inert Atoms. Remember this by thinking of the definition of Inert; meaning unable or not having the strength to move. So if it an atom has a filled outer level the electrons will be inert.
