This bind-off looks good over vertical stripes, and, while the bind-off itself is very easy, it involves two-color knitting, which is why I think this bind-off merits an “intermediate” rating.
It based on the Standard Bind-Off, which means it won’t be stretchy enough to top off two-color brioche or anything that needs to stretch much, like Fair-Isle ribbing.
The trick to this bind-off is that you knit the stitches with their opposite color while you do the Standard Bind-Off.
If you have a solid color fabric and you want to finish it with a two-colored bind-off, this is the right choice.
It’s basically the One-Over-Two Bind-Off prepared on the wrong side row and done with alternating colors.
