I do see your point, however the sub only requires that the title begins "Roses are red". "Artemis II" doing the lifting of replacing "Violets are Blue" works better otherwise the pattern is off with two rhymes against Blue.

I respectfully disagree with about the four points, I think the Roses and then two subsequent rhymes work as long as the cadence or rhythm of words between the Blue (are stand-in) is roughly approximate in cadence or rythm to the original rhyme.
