Morphology
The phrase is a straightforward adjective + noun composition: 'yellow' (a color) modifying 'marrow' (bone tissue), so the basic meaning 'marrow that is yellow' is directly derivable from the parts. Although the specific biological detail that yellow marrow is high in fat is specialist knowledge, a B1 learner who knows both words will understand the general referent, making the expression transparent.
Etymology
Yellow marrow is named for the fatty tissue inside long bones that looks yellow, like butter. Because of that image, the term means the fat-rich marrow in adults instead of the red marrow that 'makes blood'.
