Night Watch PPG 1145-7

PPG Night Watch (PPG1145-7) LRV and undertone

PPG Night Watch (PPG1145-7) is a dark color in the blue family, with an LRV of 6 and a calculated cool blue undertone. Light Reflectance Value measures the percentage of visible light a surface reflects, using a scale from 0 for absolute black to 100 for pure white. An LRV of 6 means Night Watch reflects very little light, so it can reduce the perceived brightness of a room when applied across large surfaces. Its blue classification and cool undertone help distinguish it from dark colors based on green, brown, or warm red.

Lighting can shift the appearance of dark, cool colors. North-facing daylight generally looks cooler, while south-facing daylight tends to be warmer. As a result, the surrounding light and adjacent finishes may change how the blue undertone reads. Test the paint on several walls at different times, and compare it with the intended trim. A lighter trim color can provide a clear edge against this low-LRV shade.

PPG Night Watch in other brands

The nearest listed alternative is Sherwin-Williams Cascades (SW 7623), with an LRV of 4.0 and a ΔE of 6.2. ΔE expresses the numerical difference between colors. A value below 1 means near-identical, 1 to 2 means very close, 2 to 4 means close but visibly different side by side, and above 4 means only similar. Cascades is therefore similar rather than a close match by this measure.

Behr Midnight Blue (N480-7) has an LRV of 9.0 and a ΔE of 8.4. Sherwin-Williams Cyberspace (SW 7076) has an LRV of 6.0 and a ΔE of 9.1. These options differ numerically from Night Watch despite their comparable dark values. Benjamin Moore Wrought Iron (2124-10), with an LRV of 8.17 and ΔE of 9.2, is also only similar. Compare physical samples because equal or similar LRVs do not establish matching hues.

Lighter and darker PPG alternatives

PPG Pine Forest (PPG1134-7), with an LRV of 7, is slightly lighter than Night Watch. Its ΔE of 7.9 indicates that the two colors are still noticeably different. PPG Cavalry (PPG1041-7), also at an LRV of 7, offers the same nominal light-reflectance level, but its ΔE of 10.0 likewise signals a color difference.

For a lighter option, PPG Azalea Leaf (PPG1149-6) has an LRV of 13, while PPG Knight’s Armor (PPG1001-6) has an LRV of 11. Both reflect more light than Night Watch. They may suit comparisons where a less light-absorbing finish is needed, rather than a precise blue replacement. Check samples in the room before choosing, particularly where the wall color meets trim, cabinetry, or flooring.
