Artist probing yellowish-brown and dark brown (7)
I believe the answer is:
caramel
'dark brown' is the definition.
'caramel' can be an answer for 'brown' (I've seen this before). I am not sure about the 'dark' bit.
'artist probing yellowish-brown' is the wordplay.
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'probing' is an insertion indicator (probe can mean to make a hole in).
'yellowish brown' becomes 'camel' (I've seen this in another clue).
'ra' going into 'camel' is 'CARAMEL'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for caramel that I've seen before include "Sugar solution heated till brown" , "Browned syrup" , "Chewy sweet - burnt sugar" , "Soft sweet" , "It's produced by heating sugar until brown" .)
