Due to modern manufacturing practices, cars are assembled and painted in different factories in different Countries. As a result, even though a vehicle may have the same paint code, variations in colour occur due to slight differences in formulation and application. This is especially apparent with metallic and Pearl colours.
It is common to have at least three variations and quite common to have between seven and eight variations of colour. We have seen as many as fourteen variations of a colour using the same Paint code.
Painted colour chips showing the variants are expensive to produce and lower end paint suppliers do not have colour chips of the variants. It is very difficult to keep up with the Variants as they come through and production of the matching colour chips falls behind So another method of matching the paint colour is often needed.
