Can you mix and match various manufacturers paints?

The most important rule to remember when mixing paints is to never mix enamel and acrylic paint, this is because one is oil or solvent-based whilst the other is water-based, and oil and water do not mix. Apart from that, you should be able to mix different paints from different manufacturers without any problems, just make sure you mix it thoroughly.

If there was to be a consideration given to mixing paints from different manufacturers, it would be that the shades may vary from one brand to another. This is not such a problem if you are creating a one-off mix, and you're mixing enough to complete a project, however, if you are planning to recreate the exact same shade of colour time after time then you are at the mercy of your ability to colour match. So be warned!
