When I see the KCS livery, I think of the changes that the GN made to their original scheme, simplifying it to save money in their later years. The bottom white stripe was eliminated, the double orange striping was eliminated, and the yellow striping between the orange and green striping was eliminated. It was a much less elaborate - and cheaper - paint job.
On the other hand, the KCS has the whole nine yards: black, yellow and red striping along the entire length of the engine, with a yellow stripe along the bottom, and the red trim striping all along the top and the bottom of the black striping. It's not unlike many of the details the Great Northern had before money got tight. Maybe it's a sign the KCS is doing fine financially. Then again, maybe it has little to do with it, but if they ever simplify their scheme the way Great Northern did, that may be a sign of an economic cutback. Pure speculation, but it's interesting to think about.
