The 5-point LRV gap — 25 for Treron vs 20 for Foggy Day — means Treron will open up a space more effectively. Where Treron leans warm, Foggy Day reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 14.4 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Treron vs Foggy Day in Real Spaces
3 real rooms side by side. Seeing Treron and Foggy Day 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. Treron 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. Treron has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Treron has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

Treron vs Foggy Day Simulated Comparison
5 simulated room previews — drag the slider on each to see Treron on one side and Foggy Day 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.
