Copen Blue vs Rock Candy
Both are Sherwin-Williams colors. Hue-wise, Copen Blue belongs to the blue-green family and Rock Candy to the grey family. At LRV 75 vs 59, Rock Candy will read as the brighter of the two — a 16-point gap that matters most in north-facing or low-light rooms. The tonal difference — Copen Blue's cool character against Rock Candy's neutral — becomes most visible against white trim or in morning light. At ΔE 9.2, the difference is perceptible but not dramatic — the two can work harmoniously in the same space. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Copen Blue vs Rock Candy in Real Spaces
3 real rooms side by side. Copen Blue and Rock Candy 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.
Living Room
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. Rock Candy returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The LRV gap is large enough that Rock Candy will make the room feel meaningfully brighter than Copen Blue would.
Kitchen Cabinets
On cabinetry, undertone and temperature become more pronounced against countertops and hardware. The LRV gap is large enough that Rock Candy will make the room feel meaningfully brighter than Copen Blue would.

5 simulated room previews — drag the slider on each to see Copen Blue on one side and Rock Candy 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.
