Some people primarily colder or hotter? (7)

I believe the answer is:

spicier

'hotter?' is the definition.
('spicy' can be a synonym of 'hot')

'some people primarily colder' is the wordplay.
'primarily' indicates taking the first letters.
'colder' becomes 'icier' ('icy' can be similar in meaning to 'cold').
The first letters of 'some people' is 'sp'.
'sp'+'icier'='SPICIER'

'or' is the link.

(Another definition for spicier that I've seen is " Hotter".)

I've seen this clue in The Times.
