Finding a Benjamin Moore Equivalent for Mineral
If you love Behr Mineral but need a Benjamin Moore alternative, you are not alone. This is one of the most common cross-brand paint matching searches, whether you are working with a painter who prefers Benjamin Moore, your local store does not carry Behr, or you simply want to compare prices across brands before committing.
Mineral (PPU18-20) is a dark gray with warm dark charcoal undertones. A very dark, warm charcoal-brown. Behr's answer to Iron Ore and Wrought Iron. Rich and dramatic, with brown warmth that keeps it from reading as a flat, cold black. To find a good Benjamin Moore match, we need a color that captures not just the right depth (LRV 6) but also that specific undertone character. That is where Delta E color science comes in.
We calculated the perceptual color distance between Mineral and every Benjamin Moore color using the CIE2000 Delta E formula, which measures how different two colors look to the human eye. 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 Benjamin Moore option is Wrought Iron (2124-10) with a Delta E of 3.8, which is a "good match" level match. Wrought Iron is greener. Mineral is browner. Similar depth and impact. You will want to test a sample before committing, as the difference may be noticeable in certain lighting.

Undertone Comparison
Mineral has warm dark charcoal undertones. A very dark, warm charcoal-brown. Behr's answer to Iron Ore and Wrought Iron. Rich and dramatic, with brown warmth that keeps it from reading as a flat, cold black.
Wrought Iron has warm charcoal-green undertones. A dark, complex near-black with warm charcoal undertones. Softer than a true black, with depth that changes with light.
The undertone difference is worth paying attention to. While they are close in overall appearance, the different undertones mean they may diverge in certain lighting. Mineral's warm dark charcoal quality may read differently than Wrought Iron's warm charcoal-green character, especially in rooms with strong directional light or colored accents that could pull out one undertone more than the other. Test a sample in your specific room before committing.

No, they are not identical. Mineral is a Behr color with warm dark charcoal undertones and an LRV of 6. Wrought Iron is a Benjamin Moore color with warm charcoal-green undertones and an LRV of 6.16. With a Delta E of 3.8, the difference is subtle and mainly visible in direct side-by-side comparison. Paint formulations differ between brands, so even colors with similar values can look slightly different due to pigment concentration, binders, and finish.
With a Delta E of 3.8, the difference is enough that they should not be used on adjacent walls in the same room. You can use them in separate rooms of the same house, but be aware that walking from one room to the other may reveal the difference, especially if the rooms have similar lighting. For the most consistent look, pick one brand for all connected living spaces and reserve the other brand for visually separate rooms like bathrooms or bedrooms behind closed doors.
There are several practical reasons to look for a Benjamin Moore equivalent. Price differences between brands can be significant on large projects. Availability matters if your nearest paint store or home center specializes in Benjamin Moore. Some painters have strong preferences for one brand's formula based on coverage, dry time, or workability. And if you are touching up existing Benjamin Moore work, matching within the same brand gives you the best consistency for seamless results.
