Yes thank you
there are paints for metals, paint it out in the same paint color you painted the walls.
Faux paint them marble , or whatever your imagination may inspire.... I hate them too. they limit your furniture placement. So ... try thinking outside the box...and incorporate them into your decor.... Your public library will carry DIY craft and ''how too do'' project books and guides. You might want to cover them with fabric or wallpaper that matches your wall, drapes or upholstery,, decoupage style or with a spray adhesive or school glue....have fun ...
If you do decide to spray paint them, be sure to use the heat resistant paint.
Thanks for the help found on amazon plastic covers that look nice.
