The warm brown undertone keeps it from feeling flat or lifeless. Rich and commanding. To find a good Farrow & Ball match, we need a color that captures not just the right depth (LRV 5) but also that specific undertone character. That is where Delta E color science comes in.

A Delta E under 2 means most people cannot tell the colors apart. Between 2 and 4, you might notice a difference in certain lighting. Above 5, the difference is clearly visible side by side.
The results are decent but not perfect. The closest Farrow & Ball option is Down Pipe (No.26) with a Delta E of 2.8, which is a "good match" level match. Down Pipe is the closest F&B option.

Test a sample in your specific room before committing.
