2 real rooms side by side. Seeing Treron and Capri blue in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
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. Treron reflects noticeably more light off the walls, making the space read more open than Capri blue.
Kitchen Cabinets

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