Around edges of timber noticed pale yellow colour (5)
I believe the answer is:
straw
'pale yellow colour' is the definition.
(I've seen this before)
'around edges of timber noticed' is the wordplay.
'around' indicates putting letters inside.
'edges of' means to remove the middle letters.
'noticed' becomes 'saw' (I've seen this in another clue).
'timber' with its middle taken out is 'tr'.
'tr' put within 'saw' is 'STRAW'.
(Other definitions for straw that I've seen before include "Means to absorb" , "Stalk of dry grass" , "Pale-yellow - through which one can drink" , "Animal bedding" , "Thatching material" .)
