Midnight Blue (PPU15-18) is a dark navy with blue-purple undertones. A deep, dramatic navy with subtle purple undertones. Rich and bold, with more purple lean than many navies. 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.
We calculated the perceptual color distance between Midnight Blue and every Farrow & Ball 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 Farrow & Ball option is Railings (No.31) with a Delta E of 3.5, which is a "good match" level match. Railings is the closest F&B option.

Undertone Comparison

Railings has blue-black undertones. A deep, complex blue-black. Softer than a pure black with a subtle blue undertone that gives it depth and sophistication.
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. Midnight Blue's blue-purple quality may read differently than Railings's blue-black 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.
