Olive Yellow is not a background neutral. It arrives like a flash of mustard and can carry a small interface detail all by itself.
On paper or fabric, it recalls seed pods and dry grasses. Set against inky green, it feels deliberate; against pure white, it can look almost electric.
Warm Colors and Khaki Colors keep its yellow side believable. For a bolder split, let Dark Green Colors handle the shadow around it.
