With LRVs of 18 and 18, 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 18 vs 17), so neither reads brighter in a room. A ΔE of 1.4 means the difference barely reads in a finished room.
With LRVs of 18 and 18, the two reflect almost the same amount of light. At ΔE 1.9 you'd need them side by side to tell them apart.
Their light reflectance is nearly identical (LRV 18 vs 18), so neither reads brighter in a room. A ΔE of 2.1 means the difference barely reads in a finished room.
With LRVs of 19 and 18, the two reflect almost the same amount of light. At ΔE 2.4 you'd need them side by side to tell them apart.
With LRVs of 18 and 16, the two reflect almost the same amount of light. At ΔE 2.4 you'd need them side by side to tell them apart.
Their light reflectance is nearly identical (LRV 20 vs 18), so neither reads brighter in a room. The ΔE 3.2 gap is real but not dramatic — distinct as a choice, harmonious together.
