Flagstone vs Train
Flagstone and Train come from the same PPG collection. Flagstone reads as grey, while Train reads as blue-grey — two distinct hue families, not close cousins. The 13-point LRV gap — 54 for Train vs 41 for Flagstone — means Train will open up a space more effectively. ΔE 8.2 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 10 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Flagstone vs Train in Real Spaces
10 real rooms side by side. Flagstone and Train 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. Train reflects noticeably more light off the walls, making the space read more open than Flagstone.
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. Train 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. Train 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 Train will make the room feel meaningfully brighter than Flagstone 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. Train 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. Train returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Mudroom
In a hardworking space like a mudroom, the depth and warmth of a color reads differently than in a quieter room. The LRV gap is large enough that Train will make the room feel meaningfully brighter than Flagstone would.
Patio
Exterior colors look different in open light — both tend to read lighter outside than on an interior swatch, and shadows read more strongly. The LRV gap is large enough that Train will make the room feel meaningfully brighter than Flagstone would.
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. Train returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Flagstone vs Train Simulated Comparison
5 simulated room previews — drag the slider on each to see Flagstone on one side and Train 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.
