PURPOSE: A color adjustment method for a digital broadcasting receiver is provided to minimize a video output deviation irrespective of an ADC(Analog to Digital Converter) component deviation. CONSTITUTION: An offset value and a gain value are set up(S401). A channel value of a reference color for offset adjustment is calculated(S402). The offset value is adjusted until the channel value is within a permission error range(S403-S405). The difference of channel values of reference colors for channel adjustment is calculated(S406). The gain value is adjusted until the channel value difference is within a permission error range(S407-S409). It is checked whether the channel value of the reference color for offset adjustment is within the permission error range(S411). If the channel value of the reference color for offset adjustment is within the permission error range, offset and gain adjustment values are stored(S412).
