Why Medium Gray Paint Looks Different in Person
Medium Gray paint colours are notoriously sensitive to lighting conditions and surface texture. A medium gray that reads beautifully in a north-facing room can look completely different in direct afternoon sun — which is why paint swatch decisions made under shop lighting so often disappoint.
AI paint visualisation removes this uncertainty by applying the colour to a photo of your actual doors — under your real lighting conditions — before you commit to purchase.
