Pet embellished with gold colour (5)
I believe the answer is:
taupe
'colour' is the definition.
(I know that taupe is a colour)
'pet embellished with gold' is the wordplay.
I cannot quite understand how this works, but
'gold' could be 'au' (Au is the chemical symbol for gold) and 'au' is found within the answer.
an anagram of 'pet' is 'tpe' which is within the remaining letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for taupe that I've seen before include "Brownish-grey colour" , "shade" , "Grey tinged with brown" , "colour of moleskin" , "Fifty Shades of Grey must include this" .)
