Kinda gross imagery, but I definitely saw the picture.
Still miss the punctuation, but I'm working on it.

"Why is an orange, orange
and an apple red," (This is a complete sentence and therefore should have a period. You do this often. Hell, everyone does often. Don't feel bad).
" is it the color of the skin" (Just add the capital. Think about whether a statement is finished as is. If so you MUST add the period. It doesn't change the flow of the poem).
"or a religious emblem?"

Far be it for me to tell you NOT to use punctuation, but you use the comma too often. If the sentence doesn't break and go in a slightly different direction, but continues on unabated it does not need a comma. For example, you would have used a comma after "unabated" in the previous sentence. I did not because the thought continued straight through without need of a direction change.
E.g.
"Is it just an illusion
which lures us," (this comma is unnecessary because the thought doesn't slow down. Does that make sense? Remember the old rule: "when in doubt, leave it out").
"only to lose the essence
in our greed?" (the sentence doesn't lose speed, so it needs no comma. If after "lures us" you included something like "my friend", that would have disturbed the flow of the sentence and asked for a comma).
You'll get it. Commas are hard. Start thinking about semi colons now.... they're harder. (and ignore how I use my ellipsis... it's wrong).

I believe you did really well handling such a theme. I enjoyed the extended metaphor but the message is too subtle if you haven't mentioned it at your "last few words."

I found little use of these few lines. I think they add little if any to the piece, but it is only me. I tend to brevity lately, but please don't let Wesley hear this :)

can you say why ...the rainbow always has the colors seven.... in the same order ...every time and from any where ...coz light emits refracts and has broader spectrum ...hence fruits offer variety if all was black and nothing white ...we would have been living in monotony ...with naught to compare ...so that's why nature wants to share ..and all of us humans at others glare we all love your poetic flare

loved the title. It is poetic and it sets well the reader's mood.
I only wished to see your few words added as one or two stanzas. If you think once to publish there will be 'no few words to be added there. :)
Racism and terrorism are critical issues and I believe few could handle them well.
You can do it, I trust your abilities.
