Who has never happened to "see" two colors the same in sunlight only to realize that they are actually different as soon as we enter the home or workplace?

We are talking about metamerism: two colors that appear to match only under certain lighting conditions.

In the wood coatings industry, color matching or color tolerances are definitely important. 

But what are the factors that determine metamerism? Are all colors metameric or only some? And how can this phenomenon be prevented?

In this pill, we will explain the best practices to be adopted so that metamerism is "managed" and high levels of quality can be achieved in the coating of artifacts made of wood, glass or other materials.
