I am blue
blue comes in all shades
and so do I

pastel blue, small and quiet, almost unnoticed
electric blue, loud and bright, daring
turquoise, brilliant and fun, liked by some
cobalt blue, modern and simple, unique
regular blue, unappreciated and common, nothing special
navy blue, dark and mysterious, often sad

I am every shade of blue, at one time or another
but underlying all these shades
blue will always be sad
