Medium Gray Paint on Exterior Wall — AI Visualisation Before You Commit
Choosing medium gray paint for a exterior wall is one of the most visually impactful — and most often regretted — home decisions. Paint swatches look completely different at scale, under real lighting, and on different surface textures. HouseGPTs AI Paint Designer shows you medium gray on your actual exterior wall before you open a tin.

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 exterior wall — under your real lighting conditions — before you commit to purchase.
