Earl Blue vs Black grey

At LRV 41 vs 6, Earl Blue will read as the brighter of the two — a 35-point gap that matters most in north-facing or low-light rooms. At ΔE 48.2, these are genuinely distinct colors — a strong contrast if used together, or a meaningful choice between two different directions.
