A phenomenological approach to the problem of determining the masses of pseudo-Goldstone technicolor particles is developed. The spinless bound states of the techniquarks are interpreted as elementary Higgs fields with a self-action Lagrangian which satisfies the symmetry present in practically all known technicolor models (the symmetry consists in the possibility of independent unitary rotation of all existing Higgs field doublets). An electroweak interaction destroys the postulated symmetry of the skeleton Higgs Lagrangian; a consequence is the appearance of the same 10-GeV mass for all charged pseudo-Goldstone particles. Possible mechanisms of splitting of the particle masses are considered, particularly their interaction with fermions. The characteristic splitting scale is of the order of (0.1--1) GeV. The possibility that neutral pseudo-Goldstone particles acquire mass at the expense of interaction between the particles and singlet Higgs field is discussed. Such an interaction was introduced earlier in the theory of the ''phantom'' axion. It is shown that the existence of a phantom axion should involve the existence of a ''resurrected'' axion, i.e., of a particle with the same Yukawa coupling to quarks and leptons as the standard Weinberg-Wilczek axion, but with an arbitrary mass.
