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' sounds like '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" .)
