Shade in haunted house where the symbols match (3)
I believe the answer is:
hue
'shade' is the definition.
(both can mean a colour)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for hue that I've seen before include "Shade of colour; Vietnam port" , "Colour or tint" , "Tone, shade" , "Delicate shade" , "appearance" .)
