What color and finish are the steel beams painted?

Sorry Candy. I looked pretty hard through records and couldn't anything. I remember trying different 3-4 colors. I suggest taking your laptop to the paint store and showing them the image. Another thing to bear in mind is that if you like the color you see on your computer screen, there's a good chance that doesn't match the color of the actual steel in real life. I would start with Tobacco type paint colors. I hope that helps

I'm trying to replicate a steel color as much as possible with a gray rather than a reddish brown. I have a few options from Farrow & Ball, just not able to decide on the entire thing.

Color is one of the most difficult aspects of design. I suggest you try 3-4 colors as samples adjacent to each other

What color did you use on the steel beams?

It's been a while and there were multiple tests, and some mixing going on. We have not been able to find an actual color on record. And also, the actual color in person may be different than what you see on your screen. I suggest taking your lap top to the paint store with this image.
