This note analyzes the edge density problem for directed graphs, where the chromatic number χ(D) of a digraph D is defined to be the fewest number of colours needed to colour the vertices of D so that each colour class induces an acyclic subgraph.

It is proved that the larger the Shannon capacity of $\overline{G}$ is, the larger these subgraphs are, and if $G$ is the complete graph, then some p-power of G matches the bounds of the Frankl-Wilson Ramsey construction, and is in fact a subgraph of a variant of that construction.
