I cannot understand what is the trouble, pyrometer detects invisible - IR part of spectrum, but color is visible part

В общем случае, пирометр нельзя использовать для измерения температуры раскаленных металлов. Пирометр калибруется на черном цвете. Для измерения цветных предметов необходимо корректировать пирометр под каждый цвет отдельно.

In General, the pyrometer cannot be used to measure the temperature of incandescent metals. The pyrometer is calibrated for black color. For measuring color of objects it is necessary to adjust the pyrometer for each color separately.
