of Troy:

Interesting to consider your reading of the yellow. However, no feet had trodden black the leaves on the path...

That would further indicate that the season is fall. The leaves that have fallen have not been walked over to the extent that they, through wear and weather, have not yet turned black as leaves do later in winter.

In spring, when leaves are budding out, they bud out, true, in pale chartreuse (some species), pale whitish green (white oaks), even deep red (the red maples). I don't think a yellow wood is as likely in spring as in fall.

Just my take (and respectfully),
