Check out Purl Soho's woven Field Scarf. It's in ivory, gray. And black w subtle perpendicular bands of lavender.
I believe the modification you're talking about w the yoke design chart was in in the decrease area 2/3rds of the way up. The pattern usually eliminated a MC square at the sides of the chart when there was a decrease in the previous row. At one spot the squares had to be adjusted at the end and beginning of the rows. If you just follow the main design and see where the decreases would hit so many rows up from a reference point in the design, then fill in the rest w main color stitches, you'll be fine. Nellknits did post a chart to show how the side squares should have been drawn. Her posting was in the My Progress Thread during, I believe, the third week in February. You could search under her postings.
