Get color samples to compare

We tried to investigate the use of color in a series of communication pieces, but at the moment to describe how would select and classify the samples, we found that this initial step implied a study in itself, because classifying something that is not limited in quantity (some applications working with millions of them), which has different classifications (based on culture or countries), which we hardly know a dozen names (following the studies of Bertin and Kay) and which varies depending on lighting conditions , support, or quality reproduction, requires reflection and deepening.
