Surfin' vs Undercool
Surfin' and Undercool come from the same Sherwin-Williams collection. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. The 3-point LRV gap — 49 for Undercool vs 46 for Surfin' — means Undercool 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. ΔE 7.7 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

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.
