I would like buy a product like paint in different colour which i like to use in my production, and paint will determine my product colour. I think, that the attribute is good for this. 
I could creat an attribue and Attribute set too, but Attribute Use is inactive, and if i want set my Product Attribue, i could, but Attribute Set Instance isn't mention my settings.
