Why the color ratings are not carried over is a mystery to me as it shouldn't be rocket-science.

It is not possible to carry over color ratings from LR to C1 because of the way they were implemented by adobe, not just because they are not standard IPTC fields as John mentions.
The color labels in LR are just text labels with no structure. They are not even stored in the catalog and there is no way to guarantee integrity between them in a set of images, even in the same catalog. On the other hand, if your text is "Green" then the same text is written to the xmp (xmp:Label = Green) and in the image record in the LR catalog (table: Adobe_images; field: colorLabels)
The thing is, you can have your labels set up as: green, yellow, red, etc. and tag some photos, then change the labels to: keeper, to delete, print, etc. and tag another set of photos. If you check the database or xmp files, you will find some images with red, yellow or green and another set of images with keeper, to delete or print. Moreover, I can then change the order of the colors from the LR standard 6=red & 7=yellow to 6=yellow & 7 red. If I then check the metadata in the LR catalogue or XMP file, I will just see red or yellow, how in this world would I be able to tell if that was 6 or 7? It is impossible.
In the case of C1, the color labels are structured data (not user editable) and are stored in the C1 catalog as codes (for example: ZCOLOR_TAG_INDEX=3 instead of colorlabel=yellow)
On another note, doing this exercise I might have encountered a bug in C1 version 9.1, which I tested on two computers running windows 7/64
If anybody can confirm by doing this:
- Create a new catalogue in C1
- Import one raw file (no adjustments, no external metadata)
- Assign a color label to the image in C1
- Now select File-> Load Metadata
Here I get the following warning (as in the attached image): "Metadata conflicts have been detected on a variant of image xxxx ...."
There should not be variants and the only place where the metadata was changed (color label) was in C1.
Looking at the data in the C1 catalog, there are three records in the table that holds metadata information for the variants instead of one (this is just an empirical observation, there might be valid reasons to have more than one record at this stage) and the data for color labels is different between them.
