ANSWER:

No one has the right to question Allah unless they want to reserve their seat in hell for eternity!

Why different facial features then? Why not same eye, nose, lips for all?  

All different hues have been created so that we are recognised with them, not discriminate against them. 

Such discrimination is ignorance and any such social practice is not a part of Islam.

Why did Allah even create two different color complexions(fair and dusky) ? It’s like dusky skin tones don’t get good proposals, people don’t prefer others with dusky skin tones, people with dusky skin tones aren’t allowed to have likes and dislikes of any sort when we are all equal in the eyes of Allah why this distinction at all?
