For example, stanzas 1, 3, and 5 are all shades of red, and you're using similar language (flushed, blushed, rushed to her cheeks) to describe them. I think the poem wants some more thematic differentiation there. WHY are these colors distinct? WHAT makes them different? And, additionally, you could space out the "reds" if you wanted to keep them all. Otherwise, trimming at least one out or substituting another color and emotion could be beneficial.
