Messed up WB with Rosco CTO 3/4 gels

[skysi]

I just tried Rosco CTO Cinigel 3/4 for the first time while doing a residential shoot. I put the gel on my two flashes and put my 5D on 3200K. The lighting in the house was tungsten with some daylight of a cloudy day coming in.
Shooting in the basement, I only had my flashes against tungsten light.

Funny thing was that on the camera monitor the images looked perfect. After importing into Lightroom/CDPP they are all pinkish/purplish and very hard to fix. This applies to both, shots with some cloudy daylight and shots done in the basement where there's no daylight
1. Should I have used 1/2 or perhaps full CTO.

2. Should I switch to Lee CTO? (I remember someone saying Rosco's are on a red side
3 If none of the above, what mistake am I making here?

I 'm thinking maybe it depends on the ratio of tungsten to flash?

I was shooting at: 1/40, f8, ISO 500. Both flashes were shooting in the white ceiling (one was 580EX II and the other SB 26) and were at 1/2, 1/4, sometimes the on-camera 580EX II was at full.
I could have overpowered the tungsten with other flashes that I got plenty of, but the agent wanted all the lighting fixtures of the house on and as much ambiance as possible.
Here're some examples

I have had good luck putting my WB to Tungsten and using a Rosco Full CTO. With mixed light sources this will not work though.

If you shot RAW and cannot fix it in post then you simply have too muchmixed light creeping in. You cannot have tungsten and daylight (even cloud cover) color temps in the same photo. You will always get a color cast. The only real workaround is exposing all ambient (tungsten and daylight) about 2 stops too low and using your flash for proper exposure, or using the daylight and turning off the tungsten light source.
