Colourless article about a woman (5)
I believe the answer is:
ashen
'colourless' is the definition.
(similar in meaning)
'article about a woman' is the wordplay.
'article' becomes 'an' (English indefinite article).
'about' indicates putting letters inside.
'a woman' becomes 'she' (she refers to a woman).
'an' enclosing 'she' is 'ASHEN'.
(Other definitions for ashen that I've seen before include "bleached" , "Deathly pale" , "(Of face) pale (with shock)" , "Looking pale from illness" , "Livid" .)
