With LRVs of 7 and 6, the two reflect almost the same amount of light. At ΔE 0.8 you'd need them side by side to tell them apart.
With LRVs of 8 and 6, the two reflect almost the same amount of light. At ΔE 1.1 you'd need them side by side to tell them apart.
With LRVs of 8 and 6, the two reflect almost the same amount of light. At ΔE 2.2 you'd need them side by side to tell them apart.
With LRVs of 7 and 6, the two reflect almost the same amount of light. At ΔE 3.4 they're clearly different, yet close enough to share a room.
With LRVs of 8 and 6, the two reflect almost the same amount of light. At ΔE 3.9 they're clearly different, yet close enough to share a room.
Their light reflectance is nearly identical (LRV 6 vs 5), so neither reads brighter in a room. The ΔE 4.8 gap is real but not dramatic — distinct as a choice, harmonious together.
With LRVs of 8 and 6, the two reflect almost the same amount of light. At ΔE 5.0 they're clearly different, yet close enough to share a room.
With LRVs of 8 and 6, the two reflect almost the same amount of light. At ΔE 5.5 they're clearly different, yet close enough to share a room.

Violet Blue reads slightly lighter (LRV 10 vs 6), a gap that shows most in low-lit rooms. At ΔE 7.8 they're clearly different, yet close enough to share a room.
Stiffkey Blue reads slightly lighter (LRV 10 vs 6), a gap that shows most in low-lit rooms. At ΔE 11.7 these are two genuinely different directions, not variations on a theme.
Passageway reads slightly lighter (LRV 14 vs 6), a gap that shows most in low-lit rooms. At ΔE 17.4 these are two genuinely different directions, not variations on a theme.
Their light reflectance is nearly identical (LRV 8 vs 6), so neither reads brighter in a room. A ΔE of 21.6 puts them firmly in different territory — a strong contrast if combined.
