Sapphire blue vs Basil
Sapphire blue (RAL Classic) and Basil (Sherwin-Williams) come from different manufacturers. Sapphire blue reads as blue, while Basil reads as green-grey — two distinct hue families, not close cousins. The 8-point LRV gap — 15 for Basil vs 6 for Sapphire blue — means Basil will open up a space more effectively. A ΔE of 35.6 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 6 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Sapphire blue vs Basil in Real Spaces
6 real rooms side by side. Seeing Sapphire blue and Basil 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. Basil reflects noticeably more light off the walls, making the space read more open than Sapphire blue.
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. Basil returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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. Basil 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. Basil 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. Basil reflects noticeably more light off the walls, making the space read more open than Sapphire blue.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Basil returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Sapphire blue vs Basil Simulated Comparison
5 simulated room previews — drag the slider on each to see Sapphire blue on one side and Basil 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.
