They still could have been painted on dedicated color lines and then merged 
into a single line.

Sure seems like this would waste a fair amount of paint. I assume Ford would 
have had quite a number of paint booths running in parallel, so they could 
afford to keep each booth running a single color, at least MOST of the time.

I hadn't been thinking about pressure feed guns. I LIKE calling the paint 
source the "Kitchen." It certainly makes sense to have a central location just 
keeping all the paint colors mixed and flowing.
