Two-color methods of optical control of the thermodynamic 
temperature of metals subjected to thermal treatment are analyzed. 
A technique for taking into account the nonmonochromaticity of the 
photoreception path is suggested and an analysis of methodological 
errors of two-color pyrometers with wide spectral ranges is performed 
by numerical simulation.
