A shade higher than amber? (3)
I believe the answer is:
red
'a shade' is the definition.
(red is a colour or shade)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for red that I've seen before include "Carmine" , "Colour of Merlot wine" , "Glowing" , "See it and become angry" , "eg Cardinal" .)
