Only one color, but not one size.
Stuck at the bottom, yet I easily fly.
Present in sun, but not in rain.
Doing no harm, and feeling no pain.
What Am I?
I am a home of knowledge, both banal and profound.
In grand halls and small homes I can be found.
I am a home for things of many leaves,
but my many residents are not living trees.
What am I?
