Mega Greige vs Perfect Greige
Mega Greige and Perfect Greige come from the same Sherwin-Williams collection. These are both greige-greys, so the question isn't which hue to choose — it's where within greige-grey to land. The 5-point LRV gap — 42 for Perfect Greige vs 37 for Mega Greige — means Perfect Greige will open up a space more effectively. Both share a warm character, which means they'll respond to light and surrounding materials in similar ways. ΔE 3.5 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 7 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Mega Greige vs Perfect Greige in Real Spaces
7 real rooms side by side. Mega Greige and Perfect Greige 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
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. Perfect Greige reads slightly lighter here — a subtle but real difference in how open the space feels.
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. Perfect Greige has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Perfect Greige has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
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. Perfect Greige has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
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. Perfect Greige has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
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. Perfect Greige has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Front Door
On a front door, the color is both the first and last thing you see — a context where even a modest tonal difference reads clearly. Perfect Greige reads slightly lighter here — a subtle but real difference in how open the space feels.

Mega Greige vs Perfect Greige Simulated Comparison
5 simulated room previews — drag the slider on each to see Mega Greige on one side and Perfect Greige 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.
