Plascon Micatex Paint Problem

<p>We have brought Plascon Micatex Paint from Builders Warehouse 20 Liters and started to paint our walls unitl is we ran out of paint. I went and brought 5 Liters at Chamberlain and 5 Liters at Mica all in the Silverlakes area. All the paint colors seems to differ although on the tins is all sated Umgeni Sands BBQ313. This in not acceptable as we living in the 21st century and how con the colors differ from a Standard off the shelff paint,</p>
