Mix juice and yellow colouring (8)
I believe the answer is:
jaundice
'yellow colouring' is the definition.
'jaundice' can be an answer for 'yellow' (thesaurus). I am unsure of the 'colouring' bit.
'mix juice and' is the wordplay.
'mix' indicates anagramming the letters.
'juice'+'and'='juiceand'
'juiceand' anagrammed gives 'JAUNDICE'.
Can you help me to learn more?
(Other definitions for jaundice that I've seen before include "Disorder involving yellowing of the skin" , "Disease - sour and prejudiced viewpoint" , "Condition in which skin becomes abnormally yellow" , "Yellowing of the skin and whites of the eyes" , "Illness; resentment" .)
