No, not quite. What is visible here is that a tag retrieved on a branch of a Roll-up into a new map does not import the color, although this tag (KRT) also exists in the new map that receives the Roll-up branch. Tag KRT has the same color in both maps. Tag from the Roll-up branch becomes neutral. Roll-up does not import color on the Roll-up branch and it is not possible to edit the color. As pointed out in your reply. Two equal tags (KRT) is found in the maps, but equal with same name KRT. The imported KRT neutral, the original KRT in the new map yellow. In this case, KRT in the new map is not yet used.
