Is meagre with use of colour on board (6)
I believe the answer is:
stints
'is meagre with use' is the definition.
'colour on board' is the wordplay.
'colour' becomes 'tint' (tint is a kind of colour**).
'on' indicates putting letters inside.
'board' becomes 'ss' (I've seen this in other clues).
'tint' placed within 'ss' is 'STINTS'.
'of' acts as a link.
(Other definitions for stints that I've seen before include "Is niggardly, restricts to a small allowance" , "Fixed amounts of work" , "Stretches" , "Spells" , "Allots sparingly" .)
