Chaps, we hear, making appearance (5)
I believe the answer is:
guise
'appearance' is the definition.
(I know that guise is a type of color)
'chaps we hear' is the wordplay.
'chaps' becomes 'guys' (both can mean men).
'we hear' shows a homophone (sound like).
'guys' sounds like 'GUISE'.
'making' is the link.
(Other definitions for guise that I've seen before include "Show" , "Demeanour" , "Mask" , "General appearance" , "Semblance; likeness" .)
