Wolfgang... Thank you, man. Thank you so very much. This works perfectly.

As I understand it from your correction, my mistake was that I was not doing the page break before everything else, as I should, because in any case there will always be a page break in my layout. Then, let the rest of the algorithm decide if there will be a left or right page, headers and footers, etc. Am I correct?

Thank you again for your work.

Hi List, it seems my message went unnoticed, if you can help me out, please do. I'm an struggling with this layout.

I'm trying to make something using bits and examples found here and elsewhere, but I'm hitting a wall. I know there's a flawed logic in my approach, but I can't figure it out. Any help is appreciated.

Expected behavior of the following MWE:
When starting a new chapter, check if the page is even (left page), if so, fill it with color, and start the chapter in the next odd page (right page), removing the header but leaving the footer in that start-chapter page; and if this is a start-chapter page, use a specific graphic overlay for the page, but if if not (if its a regular page), use another graphic.

Result:
The header still appears in the start-chapter page, if it comes after the color filled page. But, if the start-chapter page comes after a regular (even) page, everything works as expected (no color-filled page, no header in the start-chapter page).

MWE:

\startsetups [chapter:before]
   \doifoddpageelse
     {}
     {\pushbackground[page]
        \setupbackgrounds[page][background=color,backgroundcolor=rojo]

     \popbackground}
\stopsetups

\setuphead[chapter]
          [width=20em,
          before=\directsetup{chapter:before},
Apply the above setup with

beforesection=\directsetup{chapter:before},
