Dig ten out that are slightly coloured (6)
I believe the answer is:
tinged
'are slightly coloured' is the definition.
(I've seen this before)
'dig ten out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'dig'+'ten'='digten'
'digten' is an anagram of 'TINGED'.
'that' acts as a link.
(Other definitions for tinged that I've seen before include "Slightly tinted" , "Given slight trace of colour or quality" , "Slightly coloured" .)
