Celestial Blue vs Train
Celestial Blue (Little Greene) and Train (PPG) come from different manufacturers. Celestial Blue reads as blue-green, while Train reads as blue-grey — two distinct hue families, not close cousins. The 10-point LRV gap — 54 for Train vs 44 for Celestial Blue — means Train will open up a space more effectively. ΔE 9.4 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Celestial Blue vs Train in Real Spaces
4 real rooms side by side. Celestial Blue 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 Celestial Blue.
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.
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.
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. Train reflects noticeably more light off the walls, making the space read more open than Celestial Blue.

Celestial Blue vs Train Simulated Comparison
5 simulated room previews — drag the slider on each to see Celestial Blue 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.
