For any finite colored graph we define the empirical neighborhood measure,which counts the number of vertices of a given color connected to a givennumber of vertices of each color, and the empirical pair measure, which countsthe number of edges connecting each pair of colors. For a class of models ofsparse colored random graphs, we prove large deviation principles for theseempirical measures in the weak topology. The rate functions governing our largedeviation principles can be expressed explicitly in terms of relativeentropies. We derive a large deviation principle for the degree distribution ofErd\H{o}s--R\'{e}nyi graphs near criticality.
