...why does emulsion paint with a bit of colour cost so much.In the latest Focus DIY leaflet 10 litres of 'Crown Pure Brilliant White Emulsion' is on sale at £14.99. Thats just fine but also advertised is 2.5 litres of 'Crown Standard Coloured Emulsion' for £11.99.It doesn't matter whether the colour is the meerest hint, or a deep scarlet or whatever colour.10 ltr of coloured emulsion costs £47.96,compared to 10 ltr of white at £14.99.Surely the paint is the same,its just the addition of concentrated water soluble colour dyes,isn't it?
