Who says that leaves are green

[wapiti]

… and my colors change as seasons go.

This seems a bit vague and is an abrupt ending. Was this intentional? What was the idea you were trying to convey?

The poem itself seems to mix concepts of relativism and perceptions of reality with social mores and facts. I see the intention, but it feels a that the comparisons were really forced here.

For example:

My light may not be light for you

What does this have to do with the initial comparisons?

and another

For your green may be my blue

seems to be in relation to the beginning:

Who says that leaves are green
Or sky is blue?

This just feels awkward to me.
