I worked for a company that did this every summer. What worked best for us was:
-Having the deck painted a motif that works for all productions (usually it was wide "floor boards" and sometimes a toned down Jackson potluck style lol--always some shade of brown, cause that's what worked for our shows).
-Each show had it's own spike color, using as minimal spikes as possible.
-Each colored spike was covered with clear Marley tape (if there isn't dancing or busy foot work in the show than clear packaging tape would work in a pinch, temporarily).
-During changeovers, one person went through and covered the previous shows spikes with brown gaff tape and wrote the show number on it. And then tore the brown gaff off that next shows spikes (obviously, make a spike chart to double check).
-All immovable scenic elements were "spiked" with a sharpie or paint pen. Didn't need to cover any of these by show because they weren't noticeable from offstage in our venue.
This routine works for our team for many summers with 3-5 shows in the same space in rep.
