The default=1. -n numcolors ... NUMCOLORS is the number of colors to consider during color reduction. Values are integers>1. The default=6. -e excludecolor ... EXCLUDECOLOR is an exclude color to be ignored in getting the dominant color. Any valid opaque IM color. The default=black for -m 4; otherwise, not used. -f fuzzval ... FUZZVAL is the fuzz value for modes 2-6. Smaller values select colors closer to the mode desired, but may lead to less than the selected numcolors.
