What is the tone of the choice by Dorothy Parker?

Technicolor fantasy. it is odd the heavy use of Green in the Emerald city coud have off or unintended overtones of maybe sacrilege- there was a character who wore a green uniform with an odd hat- almost looked like a Bishop. He was stationed in the back anterooms ( almost like the vestibule of a church) of the Wizard"s palace, very interesting. I thought he was ( watchman?) a satire on St. Patrick.
