The colour circuit can be bypassed in either or both tone switch positions via internal dipswitches. When you open the pedal the switch is located just above and to the right of the stompswitch.  Depending on the compressor you may have a small piece of plastic covering the dipswitches that can be removed.  Move the top dipswitch to the left to disengage the colour circuit from the cut and move the bottom switch to the left to disengage colour from the boost.
