With LRVs of 8 and 7, the two reflect almost the same amount of light. At ΔE 0.6 you'd need them side by side to tell them apart.
Their light reflectance is nearly identical (LRV 9 vs 8), so neither reads brighter in a room. A ΔE of 1.1 means the difference barely reads in a finished room.
With LRVs of 8 and 8, the two reflect almost the same amount of light. At ΔE 2.5 you'd need them side by side to tell them apart.
Their light reflectance is nearly identical (LRV 9 vs 8), so neither reads brighter in a room. A ΔE of 2.6 means the difference barely reads in a finished room.
Their light reflectance is nearly identical (LRV 8 vs 7), so neither reads brighter in a room. The ΔE 3.2 gap is real but not dramatic — distinct as a choice, harmonious together.
A 4-point LRV gap (12 vs 8) makes Slate grey the marginally brighter of the two. The ΔE 3.8 gap is real but not dramatic — distinct as a choice, harmonious together.
Their light reflectance is nearly identical (LRV 9 vs 8), so neither reads brighter in a room. The ΔE 4.3 gap is real but not dramatic — distinct as a choice, harmonious together.
Their light reflectance is nearly identical (LRV 8 vs 7), so neither reads brighter in a room. The ΔE 6.5 gap is real but not dramatic — distinct as a choice, harmonious together.
Passageway reads slightly lighter (LRV 14 vs 8), a gap that shows most in low-lit rooms. At ΔE 12.0 these are two genuinely different directions, not variations on a theme.
