Cloud Nine vs Riverway
Both are Sherwin-Williams colors. Cloud Nine reads as white, while Riverway reads as blue-grey — two distinct hue families, not close cousins. At LRV 78 vs 16, Cloud Nine will read as the brighter of the two — a 62-point gap that matters most in north-facing or low-light rooms. The tonal difference — Cloud Nine's neutral character against Riverway's cool — becomes most visible against white trim or in morning light. At ΔE 45.1, these are genuinely distinct colors — a strong contrast if used together, or a meaningful choice between two different directions. Below you'll find 8 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Cloud Nine vs Riverway in Real Spaces
8 real rooms side by side. Seeing Cloud Nine and Riverway in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
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. Cloud Nine returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. The LRV gap is large enough that Cloud Nine will make the room feel meaningfully brighter than Riverway would.
Kitchen
Kitchen lighting tends to be bright and directional, which sharpens contrast and makes undertone differences more apparent. The LRV gap is large enough that Cloud Nine will make the room feel meaningfully brighter than Riverway would.
Dining Room
Dining room light is typically the warmest in the house, which shifts both colors toward the red end of the spectrum compared to daylight. Cloud Nine reflects noticeably more light off the walls, making the space read more open than Riverway.
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 Cloud Nine will make the room feel meaningfully brighter than Riverway would.
Home Office
In a home office, wall color sits in your peripheral vision for hours at a time, so temperature and undertone matter more than you might expect. The LRV gap is large enough that Cloud Nine will make the room feel meaningfully brighter than Riverway would.
House
At full exterior scale, the difference between these two colors becomes much easier to judge than from a small chip. The LRV gap is large enough that Cloud Nine will make the room feel meaningfully brighter than Riverway would.
Front Door
Front doors are seen in isolation against the rest of the facade, which makes them a high-stakes surface where even subtle differences matter. Cloud Nine returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Cloud Nine vs Riverway Simulated Comparison
5 simulated room previews — drag the slider on each to see Cloud Nine on one side and Riverway 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.
