Answer:
I'm really blue but when you see me I'm red. You don't see me too often. I'm there for you if you're hurt.
The more holes you cover the lower I go.
My first is in window but not in pane. My second's in road but not in lane. My third is in oval but not in round. My fourth is in hearing but not in sound. My whole is known as a sign of peace. And from noah's ark won quick release.
I move without wings between silken strings. I leave as you find my substance behind
My days are numbered.
If itβs information you seek, come and see me. If itβs pairs of letters you need, I have consecutively three. What am I?
