Icy vs Sleepy Hollow
Both from Sherwin-Williams's palette. These are both blues, so the question isn't which hue to choose — it's where within blue to land. They have nearly identical light reflectance values (56 vs 57), so they'll read as similarly Light in most lighting conditions. Both lean cool, so they'll behave similarly in mixed or changing light conditions. At ΔE 2.7, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Icy vs Sleepy Hollow in Real Spaces
2 real rooms side by side. Icy and Sleepy Hollow 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.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.
Mudroom
Mudrooms are seen in passing, often under whatever light comes through the door — a context that favors colors with some depth. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.

Icy vs Sleepy Hollow Simulated Comparison
5 simulated room previews — drag the slider on each to see Icy on one side and Sleepy Hollow 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.
