Colour of Dutch house (6)
I believe the answer is:
orange
I believe this is a double definition.
'colour' is the first definition.
(orange is a kind of colour)
'dutch house' is the second definition.
(I've seen this before)
'of' acts as a link.
(Other definitions for orange that I've seen before include "soft drink?" , "Go earn the fruit" , "Between red and yellow on the spectrum" , "Onager (anag.)" , "Fruit - part of the spectrum" .)
