inRange() can't do that, but not all hope's lost:

split your image into channels:

Mat orig; // bgr, probably
Mat chan[3];
split(orig,chan);  // chan[0]==blue, chan[1]==green, ..

apply your own operator on the channels to binarize them:

Mat bin_red = (chan[2]<20)|(chan[2]>100);  // note: single '|'
Mat bin_grn = (chan[1]<72)|(chan[1]>155);
