It is not a simile!
simile for stuck
No, "rainbow" is a noun. But you need nouns in a simile, since a simile compares two things that are not the same, but can be related in some way. You use "like" or "as" to make the comparison. The purpose for a simile is to paint a picture, to make us imagine something, by using words. So for example, we can say: "That tie-dyed shirt is like a rainbow." In other words, it is so colorful and bright that it reminds me of a rainbow. Or we could say that "Hope is like a rainbow" -- when we are discouraged and feeling depressed due to a rainy day (problems in our life), we see a rainbow and it reminds us to be hopeful, because it is beautiful and tells us the rain and the storm are over. I've given you two examples. See if you can provide the third one!
That is a good simile, yes.
very good
"As strong as a bull."
The rainbow shone as brightly as a box of brand new color pencils, each hue vivid and vibrant, creating a kaleidoscope of color in the sky.
