Colour of eminence (4)
I believe the answer is:
grey
This could be a double definition.
'colour' is the first definition.
(grey is a kind of colour)
'eminence' is the second definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for grey that I've seen before include "Aged; cloudy" , "Colour of lead" , "Black-white tone" , "Looking old" , "Sombre colour" .)
