Hi, looking at using olive tree below dado rail and suggested i use the white in the column above the dado rail which is linnet white. When I tried this it just looks white ( I don't want yellow tint or grey tint) but do want a slight contrast with the white gloss skirting and dado which I'm not sure linnet white will give me. Wondering if my tester pot is right as it does look off white on chart and samples in the shop. many thanks
