Coloured ring arranged on the nail (9)

I believe the answer is:

anthelion

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

'coloured ring' is the definition.
'anthelion' can be an answer for 'ring' (thesaurus). I'm unsure of the 'coloured' bit.

'arranged on the nail' is the wordplay.
'arranged' indicates anagramming the letters.
'on'+'the'+'nail'='onthenail'
'onthenail' is an anagram of 'ANTHELION'.

Can you help me to learn more?

(Another definition for anthelion that I've seen is " seen in the heavens".)

I've seen this clue in the Sydney Morning Herald.
