We have bought a new house and the builders will paint the rooms in whatever colours we choose - we just have to make sure they are Dulux ones because that's what they use. I have bought loads of testers and tried them on plain white A4 paper but I don't think this is going to work. As far as I know, the painters won't be using an undercoat, so any paint I choose will be going straight on to plastered walls, which obviously aren't white. Someone told me that if I try them on cardboard that would more closely mimic the results of painting on plasterboard, but I'm not sure about this. Obviously, the builders aren't going to let me on the site to put testers on the walls!!
Any ideas?
Thanks,
