We bought some Dulux Brilliant White Matt Emulsion to redecorate our living room, which is already pure white (previously decorated with Farrow & Ball All White). We thought we'd use Dulux as it's a bit cheaper and a brand leader - big mistake! The Dulux "Brilliant White" paint dried an off yellow white - a bit like a giant nicotine stain! We only painted half of the room so we can clearly see the difference between the two paints. We also used brand new brushes. Dulux shouldn't call their paint brilliant white if it's not pure white. Has anyone had a similar experience?
