I shoot in RAW and always adjust Kelvin values if necessary. However, for this shoot, I used a full cut CTS on the monolights and a full cut CTO on my shoe-mount flashes. The gels allowed me to balance my flashes to the ambient lights within a reasonable margin of error. Because the light was decently balanced, I could have done a global shift in white balance to neutralize the warmth of the predominately tungsten lights (color balancing using a grey card would have caused the tungsten lights to look white-ish), but I felt leaving the pictures warmer made the house look even more inviting.
