Blue Horizon vs Real Red
Both from Sherwin-Williams's palette. Blue Horizon reads as blue, while Real Red reads as pink-red — two distinct hue families, not close cousins. Blue Horizon (LRV 78) reflects noticeably more light than Real Red (LRV 13), a difference of 64 points that becomes especially apparent in rooms with limited natural light. Blue Horizon runs cool while Real Red is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 85.6, 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 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Blue Horizon vs Real Red in Real Spaces
3 real rooms side by side. Seeing Blue Horizon and Real Red in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
Dining Room
A dining room lit by a dimmed pendant or candles is one of the most forgiving environments for paint — warm light softens almost everything. Blue Horizon returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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. Blue Horizon reflects noticeably more light off the walls, making the space read more open than Real Red.
Front Door
A front door is a focal point — small color differences read clearly at this concentrated scale. The LRV gap is large enough that Blue Horizon will make the room feel meaningfully brighter than Real Red would.

Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
