Happy birthday @Route10 !
While searching for Billy Collins' "The Blue", I came upon "A Slash of Blue" by Emily Dickinson. Hope this makes your day more colorful.
A slash of Blue --
A sweep of Gray --
Some scarlet patches on the way,
Compose an Evening Sky --
A little purple -- slipped between --
Some Ruby Trousers hurried on --
A Wave of Gold --
A Bank of Day --
This just makes out the Morning Sky.
