Bosporus vs Loyal Blue
Both from Sherwin-Williams's palette. These are both blues, so the question isn't which hue to choose — it's where within blue to land. Bosporus (LRV 9) reflects noticeably more light than Loyal Blue (LRV 5), a difference of 4 points that becomes especially apparent in rooms with limited natural light. Both lean cool, so they'll behave similarly in mixed or changing light conditions. With a ΔE of 10.7, 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 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Bosporus vs Loyal Blue in Real Spaces
5 real rooms side by side. Seeing Bosporus and Loyal Blue in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
Living Room
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The brightness difference is modest but present — Bosporus gives the walls a little more lift.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. Bosporus reads slightly lighter here — a subtle but real difference in how open the space feels.
Bathroom

House
Seen across an entire facade, subtle tonal differences become pronounced. What reads as nearly the same on a chip often reads as clearly different at scale. Bosporus reads slightly lighter here — a subtle but real difference in how open the space feels.
Front Door
A front door is a focal point — small color differences read clearly at this concentrated scale. The brightness difference is modest but present — Bosporus gives the walls a little more lift.
