Beige or tan, eg (5)
I believe the answer is:
brown
I believe this clue is a double definition.
'beige' is the first definition.
(thesaurus)
'tan eg' is the second definition.
(tan is a kind of brown)
(Other definitions for brown that I've seen before include "Chocolate, perhaps" , "Colour (of the PM?)" , "5,27 [PRIME MINISTER]" , "Colour of toast" , "bookish father" .)
