So I need help with my poetry plz help me to add poetic devices and your ideas as to how to make It a better poem:

They pick the red and blue, and green, and purple, and black,

But almost no one like yellow,

For it cries to be the least favorite of the bunch,

But they were to see what yellow was, then it would be the most favorite color of them all,

For it would wear its bright, and glorious crown,

And would be the happiest thing in the world,

Now that you have seen what yellow way of thinking,

Consider making yellow your favorite color.
