Rainbows are colorful wonders, and the word “vibrant” emphasizes the clarity of each hue. This adjective helps to create a strong image of the rainbow in your reader's mind, and it can also show your fictional world is a beautiful place.The colours of the rainbow are Red, Orange, Yellow, Green, Blue, Indigo and Violet.When you see a waterfall, an undisturbed meadow, or the glassy surface of a lake, it might be difficult to put the beauty into words. But, thanks to the efforts of natural poets and authors, we can use words like ethereal, verdant, and pristine to describe nature's beauty.
