Colour making animal go mad (8)
I believe the answer is:
magnolia
'colour' is the definition.
(I have seen 'Creamy colour ' mean 'magnolia' so perhaps 'colour' could also mean 'magnolia')
'animal go mad' is the wordplay.
'mad' indicates anagramming the letters.
'animal'+'go'='animalgo'
'animalgo' is an anagram of 'MAGNOLIA'.
'making' is the link.
(Other definitions for magnolia that I've seen before include "Creamy colour" , "Omani lag (anag)" , "Fragrant bloom and ubiquitous paint colour" , "Fragrant blooms might strangely gain loam" , "Fragrant bloom and popular paint colour" .)
