Treron vs Oslo
Treron (Farrow & Ball) and Oslo (Jotun) come from different manufacturers. Treron reads as greige-grey, while Oslo reads as blue-grey — two distinct hue families, not close cousins. The 14-point LRV gap — 25 for Treron vs 11 for Oslo — means Treron will open up a space more effectively. Where Treron leans warm, Oslo reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 22.6 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 Oslo in Real Spaces
3 real rooms side by side. Seeing Treron and Oslo 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 reflects noticeably more light off the walls, making the space read more open than Oslo.
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 returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

5 simulated room previews — drag the slider on each to see Treron on one side and Oslo 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.
