Cascade Green vs Opaline
Cascade Green and Opaline come from the same Sherwin-Williams collection. These are both green-greys, so the question isn't which hue to choose — it's where within green-grey to land. The 30-point LRV gap — 73 for Opaline vs 43 for Cascade Green — means Opaline will open up a space more effectively. Both share a neutral character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 18.0 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Cascade Green vs Opaline in Real Spaces
2 real rooms side by side. Seeing Cascade Green and Opaline 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
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. Opaline reflects noticeably more light off the walls, making the space read more open than Cascade Green.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Opaline returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

5 simulated room previews — drag the slider on each to see Cascade Green on one side and Opaline 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.
