Query: Colored dark matter   The idea is considered that a classical non-Abelian gauge field can be
considered as a dark matter candidate. It is shown that Yang-Mills equations
have solutions with such distribution of the mass density that allows to
describe a rotational curve of spiral galaxies. The conditions necessary for
such consideration are considered. One parameter is estimated from Yang-Mills
equations and from astrophysical observations (stars rotation curve). The
agreement is to within 1%.
