I call out for some shade (5)
I believe the answer is:
lilac
'some shade' is the definition.
(lilac is a shade of purple)
'i call out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'i'+'call'='icall'
'icall' is an anagram of 'LILAC'.
'for' acts as a link.
(Other definitions for lilac that I've seen before include "Shrub with fragrant purplish or white flowers" , "Light purple - flowering tree" , "Pale pinkish-violet" , "Shrub with fragrant pink, purple or white flowers" , "Fragrant, pale purple flower" .)
