Cobalt Stone vs Hyper Blue

Cobalt Stone (LRV 14) reflects noticeably more light than Hyper Blue (LRV 10), a difference of 4 points that becomes especially apparent in rooms with limited natural light. With a ΔE of 11.3, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
