Blue Grotto vs Blueblood
Blue Grotto and Blueblood 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 NaN-point LRV gap — 7 for Blueblood vs NaN for Blue Grotto — means Blueblood 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 12.7 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Blue Grotto vs Blueblood in Real Spaces
2 real rooms side by side. Seeing Blue Grotto and Blueblood 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. The distinction reads clearly at room scale, making the choice between them concrete.
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. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.

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