Contractor faux pas

Submitted to Product Chat

Hello so sorry—I have another question please.

I am dismayed by my contractors mismatching this installation with the light fixture template mount. It appears to be a white composite. Sadly its a eyesore with a frontal view.

How would you suggest trying to makes it less unmatched....could the visible white be touched up with primer and paint brush carefully
( masking) with the actual electrical fixture in place?
If so what paint on products would you recommend?
I do have both oil based and acrylic Ultra Cover.
Just saying... I ❤️ Ultra Cover.

THANK YOU for the opportunity to review my situation. This has bother me for more than 4 years.....
