Contraflow situations other than DDIs

I have thought for a long time that some kind of standard pavement marking should be defined for this kind of thing, particularly where a median or other barrier wouldn't be practical.  Perhaps a red stripe, sandwiched between a double yellow or white stripes.  This would permit untangling of left-turn movements at some pairs of intersections (such as at a tight diamond).

Yellow on the outsides, double white in the middle with raised white reflector posts separating traffic is how I'd do it. I've never seen an actual standard for this.

Quicksilver is an old-timey name for the element mercury (Hg).
