Wasn't able to get a custom white balance (wasn't on the shoot, so I couldn't make the DP do it), but did black balance before shooting. Magenta is going to haunt me forever.
We have been using a couple C100IIs and a C300II for a few years and recently added a C200 to the mix. Our first C200 had a bad sensor (returned and replaced) and the second one's color just seems... off. Have not been able to get good results at all, everything comes out too red/purple-y...
