I picked up a CV 35mm Color-Skopar recently and was disappointed when the right edge had a lot of magenta bleeding into it. Until someone set me straight and suggested coding the lens as a 28mm. Today I took the CV and the 35mm Perar out for some testing. Not scientific by any means, but I think they show the benefits of coding and which codes seem to work best.
The M 240 was set to a custom white balance as the snow and shade poured a lot of blue into the scene. IS0 320; Aperture Priority mode, +1.3 exposure, handheld. Both lenses shot at the max aperture, 2.5 and 3.5 respectively. RAW exported with no changes from Lightroom 5.7.
Lens name and number, with help from the Leica Lens Codes.
Voigtlander Color-Skopar 35mm f/2.5 results
To my eyes, 1., 4. and 6. look the best. The edges are going slightly towards green and there still is a hint of magenta, but compared to uncoded or coded as a 35mm, the results are much better.

MS Optical Super Triplet Perar 35mm f/3.5 results
Again, 1., 4. and 6., seem the best to me. While not perfect, they have the base balance of color and will need the least correction. I suspect at f/5.6 - 8 the color would improve even more as vignetting lessens.
