If a flower were orange would it more likely be pollinated by insects or by the wind give at least one reason for your answer

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.
