Icelandic vs Rhythmic Blue
Both are Sherwin-Williams colors. These are both blues, so the question isn't which hue to choose — it's where within blue to land. With LRVs of 67 and 69, they'll behave almost identically in terms of how much light they reflect back into a room. They share a cool quality — useful to know if you're layering them in the same space. With a ΔE of 1.3, the difference is subtle — you'd need them side by side to reliably tell them apart. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Icelandic vs Rhythmic Blue in Real Spaces
1 real room side by side. Icelandic and Rhythmic 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.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.

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