Coral Reef vs Tidewater
Both are Sherwin-Williams colors. Hue-wise, Coral Reef belongs to the pink-red family and Tidewater to the blue family. At LRV 65 vs 29, Tidewater will read as the brighter of the two — a 36-point gap that matters most in north-facing or low-light rooms. The tonal difference — Coral Reef's warm character against Tidewater's cool — becomes most visible against white trim or in morning light. At ΔE 55.9, these are genuinely distinct colors — a strong contrast if used together, or a meaningful choice between two different directions. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Coral Reef vs Tidewater in Real Spaces
4 real rooms side by side. Seeing Coral Reef and Tidewater 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. Tidewater 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 Tidewater will make the room feel meaningfully brighter than Coral Reef would.
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 Tidewater will make the room feel meaningfully brighter than Coral Reef 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. Tidewater returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Coral Reef vs Tidewater Simulated Comparison
5 simulated room previews — drag the slider on each to see Coral Reef on one side and Tidewater 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.
