Scale changes what a white finish does. A small white pot is a detail; a six-foot white trough is a surface, and it will be the brightest thing in most schemes. That is usually the point, but it means the surrounding materials have to carry the warmth, which is why large white planters sit better against timber, brick and planting than against more white.
There is a genuine practical gain at this size. A pale surface absorbs less sun than a dark one, so on an exposed terrace or roof the root zone runs cooler, and that matters more the larger the soil volume. The trade is visibility of marks: a large pale wall shows dust and splash that the same finish would hide on a small planter, so plan for an occasional wipe with mild soap and water.
