Colour of container on top of table (4)
I believe the answer is:
tint
'colour' is the definition.
(tint is a kind of colour)
'container on top of table' is the wordplay.
'container' becomes 'tin' (tin is a kind of container**).
'on top of' says to take the initial letters (I've seen 'on top' mean this).
The first letter of 'table' is 't'.
'tin'+'t'='TINT'
'of' acts as a link.
(Other definitions for tint that I've seen before include "Hue, shade" , "Hair dye" , "Shade; colour slightly" , "A slighth shade of colour" , "A slight shade of colour" .)
