In a recent work, Banks, Panzer and Pym have shown that the coefficients appearing in Kontsevich's celebrated deformation quantization formula are linear combinations of MZVs. We explain a generalization to the setting of deformation quantization in the presence of branes (in the sense of Cattaneo-Felder), where MZVs are replaced by coloured MZVs.
