Sapphire Splendor vs Dix Blue
Sapphire Splendor (Dulux) and Dix Blue (Farrow & Ball) come from different manufacturers. Both sit in the blue-grey family, which is useful context if you're narrowing within a single hue direction. The 36-point LRV gap — 41 for Dix Blue vs 5 for Sapphire Splendor — means Dix Blue 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 43.7 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Sapphire Splendor vs Dix Blue in Real Spaces
4 real rooms side by side. Seeing Sapphire Splendor and Dix 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
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. Dix Blue reflects noticeably more light off the walls, making the space read more open than Sapphire Splendor.
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. Dix Blue 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 Dix Blue will make the room feel meaningfully brighter than Sapphire Splendor 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. Dix Blue returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

5 simulated room previews — drag the slider on each to see Sapphire Splendor on one side and Dix Blue 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.
