Interface Tan vs Major Blue in Real Spaces
4 real rooms side by side. Seeing Interface Tan and Major Blue in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
Kitchen
Kitchen lighting tends to be bright and directional, which sharpens contrast and makes undertone differences more apparent. The LRV gap is large enough that Interface Tan will make the room feel meaningfully brighter than Major Blue would.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The LRV gap is large enough that Interface Tan will make the room feel meaningfully brighter than Major Blue would.
Home Office
In a home office, wall color sits in your peripheral vision for hours at a time, so temperature and undertone matter more than you might expect. The LRV gap is large enough that Interface Tan will make the room feel meaningfully brighter than Major Blue would.
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 Interface Tan will make the room feel meaningfully brighter than Major Blue would.

Interface Tan vs Major Blue Simulated Comparison
5 simulated room previews — drag the slider on each to see Interface Tan on one side and Major 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.
