According to a first aspect the present invention there is provided a composition comprising a paint and a secondary dye, the secondary dye being a first colour in a liquid phase with the paint and a second colour in a dry phase with the paint.
The addition of the secondary dye into the paint composition allows for obvious visual examination cheap oil paintings on whether or not a paint coat is being evenly applied even as a top coat over a lower coat which is of the same colour as the dried composition. When the secondary dye changes to another colour in the dried phase, the composition will then be in a finished colour which of course would have to be the desired paint colour.
The secondary dye will often oil paintings be substantially colourless or white when in said dried phase, thus allowing the paint to provide the finished colour.
The secondary dye will normally be an additive hand-painted oil painting to a base paint which base paint can be prepared by normal methods. Alternatively, the basic paint could be modified such that one of the components of the base paint becomes the secondary dye and this modified component looses its colour as the paint dries. For example, that part of the alkyd monomer dispersed in the paint is coloured and becomes transparent upon polymerisation.
