Hello, we are in a semi detached house and are painting our exterior white. The neighbour's house is white but is was painted a long time ago and they don't know what paint was used. There is a sale on for Dulux Pure Brilliant White but I worry that this will be a bit glaring/harsh. We can also colour match Little Greene Loft White, which seems softer. I am just worried that after a few weeks of harsh weather/rain, PBW will look less glaring and we are speeding up the ageing process by using Loft White? Does anyone have any views or experience with either colour? Thanks so much for your time.
