I have a front mugen rep bumper lip that I can’t decide which way I should paint it I’m referring the two lip ends on each corner normally they should be left black and whatever color your car is for the rest but I think painted all white looks nice also what do you guys think ? I just colored in the ends white photoshop

This is the way it is normally painted everywhere

Painted all white I kind of like this look

 

If you like it all white then why worry about what someone else thinks?
It's your car, do what you want.
If you want to test it, those small areas could easily be vinyl wrapped to change the appearance.
