Blue Horizon vs Watery
Blue Horizon and Watery come from the same Sherwin-Williams collection. These are both blues, so the question isn't which hue to choose — it's where within blue to land. The 20-point LRV gap — 78 for Blue Horizon vs 57 for Watery — means Blue Horizon will open up a space more effectively. Both share a cool character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 10.9 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 7 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Blue Horizon vs Watery in Real Spaces
7 real rooms side by side. Seeing Blue Horizon and Watery 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
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. Blue Horizon reflects noticeably more light off the walls, making the space read more open than Watery.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Blue Horizon returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Blue Horizon returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Dining Room
Dining rooms often rely on warm incandescent or candlelight, which flatters warm undertones and mutes cool ones. The LRV gap is large enough that Blue Horizon will make the room feel meaningfully brighter than Watery would.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. 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
A full exterior is the most demanding test for a paint color — scale and outdoor light both amplify differences that seem small on a swatch. Blue Horizon returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Front Door
On a front door, the color is both the first and last thing you see — a context where even a modest tonal difference reads clearly. Blue Horizon reflects noticeably more light off the walls, making the space read more open than Watery.

Blue Horizon vs Watery Simulated Comparison
5 simulated room previews — drag the slider on each to see Blue Horizon on one side and Watery on the other.
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.
