I really liked the main idea that you had and the symbols you used relating the the "taste the rainbow" slogan. However, you poem didn't really flow. I think you need to work on the format because the rhythm seems to be nonexisting or just all over the place.
I did enjoy these lines,
"Discrimination
The word tastes like bitter espresso
On my tongue"
But I think a better way to have written it would be perhaps,
"the word tastes like
bitter espresso on my tounge"
I see what you were trying to do, but it didn't quite flow.
I also admired the last two lines,
"That we all come from the same
Rainbow"
that was a meaningful and conclusive way to end the poem.
overall, well done
