Party symbol linked to US election showing full spectrum? (7,7)
I believe the answer is:
primary colours
'party symbol linked to us' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'election showing full spectrum?' is the wordplay.
I cannot really understand how this works, but
'election' could be 'primary' (primary is a kind of election) and 'primary' is found within the answer.
The remaining letters 'colours' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for primary colours that I've seen before include "a range of artists?" , "Eg, red, green and blue" .)
