The existence of a  Hückel--Debye color screening is often proposed as a signal of the presence of a QCD plasma. Here the particular case is examined where the quark density is largely dominant over the gluon density. In this case the two body correlation shows a spatial decay like  exp [-ar^2/3] /r to be compared with the usual electric case  exp  [-ar] /r . The usual electrodynamical case is rapidly re-examined in order to compare it with the chromodynamical case.
