Abstract Colour confinement is only a supposition, which has not yet been proven in QCD. Here we propose that macroscopic quark--gluon plasma in astrophysics could hardly maintain colourless because of causality. It is expected that the existence of chromatic strange quark stars as well as chromatic strangelets preserved from the QCD phase transition in the early Universe could be unavoidable if their colourless correspondents do exist.
