Blue Horizon vs Gladiola
Blue Horizon and Gladiola come from the same Sherwin-Williams collection. Hue-wise, Blue Horizon belongs to the blue family and Gladiola to the pink-red family. The 57-point LRV gap — 78 for Blue Horizon vs 20 for Gladiola — means Blue Horizon will open up a space more effectively. Where Blue Horizon leans cool, Gladiola reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 77.9 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 10 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Blue Horizon vs Gladiola in Real Spaces
10 real rooms side by side. Seeing Blue Horizon and Gladiola 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 Gladiola.
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 Gladiola 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.
Home Office
Home office walls matter more than most — you're looking at them all day, and a color that reads fine at first can become tiring over time. Blue Horizon returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Mudroom
In a hardworking space like a mudroom, the depth and warmth of a color reads differently than in a quieter room. The LRV gap is large enough that Blue Horizon will make the room feel meaningfully brighter than Gladiola would.
Patio
Exterior colors look different in open light — both tend to read lighter outside than on an interior swatch, and shadows read more strongly. The LRV gap is large enough that Blue Horizon will make the room feel meaningfully brighter than Gladiola would.
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 Gladiola.

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