It may bring colour to a typist's work (6)
I believe the answer is:
ribbon
This could be a double definition.
'it may bring colour' is the first definition.
The definition suggests a singular noun which matches the answer.
'typist's work' is the second definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'to a' is the link.
Can you help me to learn more?
(Other definitions for ribbon that I've seen before include "Narrow strip of coloured cloth, worn as ornament" , "Material tied in a bow, perhaps?" , "Headband" , "Fabric woven in strip" , "Thin strip of cloth" .)
