Clam Shell vs Artichoke
Clam Shell (PPG) and Artichoke (Sherwin-Williams) come from different manufacturers. Hue-wise, Clam Shell belongs to the greige-grey family and Artichoke to the grey family. The 3-point LRV gap — 21 for Artichoke vs 18 for Clam Shell — means Artichoke will open up a space more effectively. A ΔE of 10.4 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 6 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Clam Shell vs Artichoke in Real Spaces
6 real rooms side by side. Seeing Clam Shell and Artichoke 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. Artichoke 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. Artichoke 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. Artichoke 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. Artichoke 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. Artichoke 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. Artichoke reads slightly lighter here — a subtle but real difference in how open the space feels.

Clam Shell vs Artichoke Simulated Comparison
5 simulated room previews — drag the slider on each to see Clam Shell on one side and Artichoke 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.
