紅葉 is the general term for autumn leaves or the changing of colors, while 山粧う specifically personifies the mountain as dressing itself in those colors, a poetic and seasonal image.
Compound of 山 (mountain) and 粧う/装う (to dress up, to adorn). The phrase personifies the mountain putting on its autumn foliage as if dressing in fine clothes. The exact origin is uncertain, but it is a classical poetic expression.
