Either separate your Colours in user prefs.....or select your fixtures spin Cyan all the way to full, then hold down the Backspace and touch the Magenta and Yellow to knockout their values, then Record to a Master....set IPCB......rinse and repeat for Magenta, Yellow, CTO, CTB.....etc, etc.
Make sure you set any of your other cuelists with color info to Persist on Override if you want them to return to their color when you are done with IPCB.
