Benjamin Moore Black Onyx (2133-10)

| |

Benjamin Moore Black Onyx is a dark black with little to no undertones. If you are looking for a good black paint color that won’t look blue, green or anything in between this is it!

When we moved to Tennessee we had a daunting task ahead of us…repainting the exterior of our wooden board and batten barn and shop. While I love the board and batten exterior I was not a huge fan of the exterior colors – chocolate brown with a red roof. It just didn’t feel like us and our style. I knew I wanted to paint it, but what color?

The color selection was something I wanted to get just right as I didn’t want to have to re-do this project because I chose the wrong color. I looked at painting it white, gray, a blue-gray, an earth tone green and finally black. Well, the black barn color selection won and I couldn’t be happier with the results.

However, the task was just beginning! I knew I wanted a black barn with a gray metal roof, but there are like a ZILLION BLACK COLORS out there…what color to chose?

I did share some of the black paint colors we researched and tested and will break them down in comparison to BM Black Onyx for you here.

Black Onyx for Interiors

Can you paint an interior wall or room black? Sure you can! And it looks amazing. When we purchased our first home back in, that was a long time ago, I painted our powder room black and I LOVED it! I have no idea of the exact paint color, but it was stunning to say the least.

BM Black Onyx is amazing in a room that has a lot of windows or even in a room without any windows but that has a ton of lighting. Black Onyx looks best with either natural or artificial light as Black Onyx craves light and looks amazing when given what it needs. Onyx would also look great on kitchen or office cabinets or on the interior of a front door.

Black Onyx on Furniture

Onyx looks great on furniture too. I used BM Black Onyx on my antique buffet I found on FB Marketplace. Onyx looks amazing on kitchen cabinets or office built-ins. Using either BM Advance Paint for furniture or SW Emerald paint will give you an ideal finish on your furniture or cabinets.

Black Onyx for Exteriors

Dark exteriors are very popular right now and on trend. They are gorgeous and even though they are on trend now black barns have been around a long time. I love to pull from timeless designs of the past while designing for the current. Trends come and go but certain historical designs are timeless. Dark paint colors, such as Onyx, look great without trim as we have on our barn and hope. It also looks fabulous with lots of foliage as contrast. Consider warmer whites or light gray paint colors for an accent color if necessary. We love the light gray metal roof on our barn as it looks fabulous with the black board and batten.

Final Thoughts on Black Onyx

With so many wonderful black paint colors to chose from you can’t go wrong with Black Onyx. However, testing before you paint is crucial. There were so many shades of black I just knew was going to be the right black hue for our barn and it ended up not being right at all for our needs and setting. Although every color we tried was a gorgeous color it wasn’t quite what we were looking for. Black Onyx gave us the exact shade of black we were looking for with no undertones and a black color that wasn’t too black. We love it!
