When I rearrange at least one of the first pictures of an image list, a new collage picture will be created and there are usually no pale pictures anymore. As soon as I restore the order of the pictures like it was before, then the old pale collage picture will be loaded again.
It's similar to item lists: When I rearrange the first items of the list, a new collage will be created - usually without pale pictures. Sometimes I also have to change the default thumbnail image to get a new collage picture.
A solution could be to delete all older collage pictures - they should be created automatically after loading a list of lists. Newly created collage pictures are not pale.
