Church canon with a new description of the heavens? (8)

Ross

I believe the answer is:

cerulean

I'm a little stuck... Click here to teach me more about this clue!

'description of the heavens?' is the definition.
'cerulean' can be an answer for 'heavens?' (thesaurus). I'm unsure of the 'description of the' bit.

'church canon with a new' is the wordplay.
'church' becomes 'CE' (abbreviation for Church of England).
'canon' becomes 'rule' (canon can mean a rule or principle).
'with' is a charade indicator (letters next to each other).
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'ce'+'rule'+'a'+'n'='CERULEAN'

Can you help me to learn more?

(Other definitions for cerulean that I've seen before include "Light shade of blue" , "Blue like the sky" , "Sky-blue in literary way" , "Sky-blue for Laurence" , "Deep blue colour" .)
