Giovanni,
This last is only true if a less transparent yellow is used. With a
transparent yellow, the yellow can come anywhere. I usually print yellow
first, just because that's what I do not because it doesn't work over
other colors, but I do have one example where I printed yellow last.
For the apricots on my home page, an early tricolor:

I decided after printing the three colors that another yellow printing
was indicated to get the color the way I wanted. So I printed yellow
over the three colors. Tou can see that even in the darkest parts of the
picture, the yellow overlay is simply not a problem.
