Blue Grotto vs Jay Blue
Both from Sherwin-Williams's palette. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. Jay Blue (LRV 9) reflects noticeably more light than Blue Grotto (LRV NaN), a difference of NaN points that becomes especially apparent in rooms with limited natural light. Both lean cool, so they'll behave similarly in mixed or changing light conditions. The ΔE 7.3 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Blue Grotto vs Jay Blue in Real Spaces
1 real room side by side. Blue Grotto and Jay Blue are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Front Door
A front door is a focal point — small color differences read clearly at this concentrated scale. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.

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