Said the man's name could be Black or Brown (3)
I believe the answer is:
hue
'name could be black or brown' is the definition.
I can't tell whether this defines the answer.
'said the man's' is the wordplay.
'said' shows a homophone (sound like).
'the man' becomes 'Hugh' (man's name).
'hugh' is a homophone of 'HUE'.
Can you help me to learn more?
(Other definitions for hue that I've seen before include "General hubbub - . . . and cry" , "Tone, shade" , "Shade of colour; Vietnam port" , "General outburst of alarm or protest - . . . and cry" , "Colour or tint" .)
