I am painting a bedroom which I have undercoated with a white anti-mould paint. I have bought magnolia matt paint to paint over this but it shows up as a deep orangy/beige colour? However, if I put the magnolia paint on to say a piece of cardboard it comes up with a light creamy warm white shade which is the colour I am looking for.
Do you have any ideas of how I can get around my problem? I have tried various brands of magnolia. Should I try a dark undercoat first before applying the magnolia?
Any advice would be most welcome.
