“I just want the shutters to be black”. I often get that line when choosing colors for common house parts. Blacks have quite a range when it comes to paint color. They can go gray, blue, brown and even purple. One of the most common black colors I use for exterior is Sherwin Williams 6258 Tricorn Black. Looks fab on doors, trim and yes, shutters. I also like it on furniture. Although I have never tried it, the hue would look stunning in an entry. Check it out.
