GH2 Matching 14-140 and Canon FD

I use a 14-140 for my B camera at weddings. It is the most flexible and dependable lens for a B camera to have. So I begrudgingly continue to use it. With my A camera, I'm on a Canon FD 50mm. I do my best to match the very different color profiles of these lenses, but was curious if anyone has any tips on how they work with this.

Things I do but still need improvement and advice:

1. I desaturate the Canon a little bit.
2. There's always this warmness, which I love, but perhaps too much of a redness. For people with light skin it can be unflattering at times... I'm sure there's some really good ways to deal with this with the multitude of color correction options in Premiere Pro, however, beyond Curves, HLS and Fast Color Corrector, I don't really know what else to employ (I'll be youtubing color correction tutorials in the meantime).
3. Not sure how to match contrast as honestly, with the colors being so off, I don't know how to see the difference.
4. I boost the saturation of the 14-140, which is a mild improvement, and warm the white balance to red, again, mild improvement if any.
5. There's of course also a green tint with the 14-140, though I know I've heard there's a favor to the greens with the Panasonics. In any event, seems to be more prevalent with the 14-140.

So if anyone also works with similar combinations of Panny lenses with Canon FDs I'd love to hear what anyone else does. Bonus if people have tips for matching the Voigtlander 25mm with Canon FDs.

Thanks in advance!
 
0.0 before filming do white balance setting on camera on each scene with different lighting sources
0.1 overall camera modes settings must be also matched prior to filming

2+3 but how to see difference - need to research one good word "VectorScope"

if want to see color difference between your lenses - then do test charts shots in controlled environment with same settings (also as lens settings: aperture/zoom/focus ) on single camera.
after that do substraction between images and save for reference.
saved reference use for adjusting preset of color corrector "lens matching"(if substraction to black - preset curves must give black image, if substracted and inverted to white - then white ). work must be done very precisely.

that operation where numeric value of each pixel (each of chanels RGB, not as one single value) from one image is mathematicaly substracted from the same located pixel of second image (as you can understand: images must be well aligned for such procedure).
that in different softwares may be named differently. main idea in all of them is overlaying one over another with mathematical sign "-"

even simpliest paint.net have such operation :
- background = image1
- add layer and set it property to "Difference"
- paste into it image2
- ALIGN
= result - full black (almost, as digital noise) = no differences, otherwise image with color shift map, which can be measured, or reworked to desired curve
