Treron vs S 1502-Y in Real Spaces
4 real rooms side by side. Seeing Treron and S 1502-Y 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
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. S 1502-Y 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 room light is typically the warmest in the house, which shifts both colors toward the red end of the spectrum compared to daylight. S 1502-Y reflects noticeably more light off the walls, making the space read more open than Treron.
House
At full exterior scale, the difference between these two colors becomes much easier to judge than from a small chip. The LRV gap is large enough that S 1502-Y will make the room feel meaningfully brighter than Treron would.

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.
