It's hard to see the difference between clay paints like Auro 535 clay colours, or Auro 331 white over a natural emulsion such as Auro 555 colours, or Auro 524 white, but there is a difference.
Looks: Fundamentally, the Auro clay paints are more of a matt finish, and look slightly flatter and more velvety than the normal emulsions like the Auro 555.
Durability: The clay paints are not as durable, the white clay Auro 331 and the coloured Auro 535 having a wet scrub resistance of class 3, whereas the Auro white emulsion is class 1, and the Auro 555 colours are class 2.
Summary. Clay is flatter, more matt and a lovely finish, but not as durable or wipeable like the rest.
