Colour that is away from cue ball (3-5)
I believe the answer is:
off-white
'colour' is the definition.
(off-white is a kind of colour)
'away from cue ball' is the wordplay.
'away from' becomes 'off' (eg off work).
'cue ball' becomes 'white' (white ball in cue sports).
'off'+'white'='OFF-WHITE'
'that is' is the link.
(Other definitions for off-white that I've seen before include "Very slightly yellowish or grey" , "something like cream" , "Very pale tint" , "Slightly-tinted colour" , "Colour such as cream or bone" .)
