Arched face frame

Novice woodworker here; thank you in advance for any suggestions you might have.
I’m making a face frame for a display cabinet, using wood from my local box store. I used oak plywood to make an arched top, and red oak lumber for the side pieces.
I joined them and then stained with Minwax Wood Finish oil-based stain, Honey.
The problem is that they don’t look the same. Is there a way to fix this now?
