Light Blue vs Pure White
Where Light Blue belongs to Farrow & Ball's range, Pure White is a Sherwin-Williams color. Light Blue reads as blue-green, while Pure White reads as beige-greige — two distinct hue families, not close cousins. Pure White (LRV 84) reflects noticeably more light than Light Blue (LRV 49), a difference of 35 points that becomes especially apparent in rooms with limited natural light. Light Blue runs neutral while Pure White is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 17.7, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
