Healthy colour (4)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
pink
This clue is a double definition.
'healthy' is the first definition.
(thesaurus)
'colour' is the second definition.
(pink is a kind of colour)
(Other definitions for pink that I've seen before include "like the Financial Times?" , "Left-wing" , "Colour; herbaceous plant" , "Colour it's healthy to be in" , "left of centre?" .)
