# A relaxation of proper coloring

I am wondering if the following relaxation of proper coloring appears somewhere. I have tried some searching and have found a few relaxations of proper coloring, but none the coincides with what I have below.

Let $G = (V,E)$ be a graph (or $H = (V, E)$ a hypergraph). Let $E = A_1 \uplus A_2 \uplus \cdots \uplus A_l$ be a partition. I am looking at coloring of the vertices such that for each $1 \leq i \leq l$ there exists some $e \in A_i$ where $e$ is not monochromatic. Notice we recover the standard notion of proper coloring by partitioning $E$ into singletons.
