Can a coat-tail have a touch of colour? (4)
I believe the answer is:
tint
'colour?' is the definition.
(tint is a kind of colour)
'can a coat-tail' is the wordplay.
'can' becomes 'tin' (both are metal containers).
'tail' indicates one should take the final letters.
The last letter of 'coat' is 't'.
'tin'+'t'='TINT'
'have a touch of' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for tint that I've seen before include "Hair dye" , "Hue, shade" , "Quality of colour" , "A slight shade of colour" , "(Softer variety of) colour" .)
