Armadillo vs Riverway
Armadillo and Riverway come from the same Sherwin-Williams collection. Armadillo reads as greige-grey, while Riverway reads as blue-grey — two distinct hue families, not close cousins. The 13-point LRV gap — 29 for Armadillo vs 16 for Riverway — means Armadillo will open up a space more effectively. Where Armadillo leans warm, Riverway reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 20.4 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 8 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Armadillo vs Riverway in Real Spaces
8 real rooms side by side. Seeing Armadillo 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
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. Armadillo reflects noticeably more light off the walls, making the space read more open than Riverway.
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. Armadillo returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Armadillo returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Dining Room
Dining rooms often rely on warm incandescent or candlelight, which flatters warm undertones and mutes cool ones. The LRV gap is large enough that Armadillo will make the room feel meaningfully brighter than Riverway would.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. Armadillo returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Home Office
Home office walls matter more than most — you're looking at them all day, and a color that reads fine at first can become tiring over time. Armadillo returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
House
A full exterior is the most demanding test for a paint color — scale and outdoor light both amplify differences that seem small on a swatch. Armadillo returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Armadillo vs Riverway Simulated Comparison
5 simulated room previews — drag the slider on each to see Armadillo 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.
