Take note .... Paint manufacturers have different base paints, then there are a range of bases generally 1 to 4 , then each manufacturer will vary the ingredients within their paint. So if you love a colour from 'UNREAL Paints' DO NOT get it made up by 'SUPER Paints'.
See the image below for variance in colour using different base paints .... uugghh. Just one coat of each and you can see the difference.
