There is also the "mercury lamp" in "Rose Girl". The characters in the old animation are all set in that color, which is quite early, so there are not many pictures. If you can have more pictures, you may see them more clearly.
These may have been posted by everyone themselves, so the colors and the like have changed slightly.
I hope it helps you ~ I will continue to add questions when I think of other cartoons where Lori wears purple skirts.
