Similar type and colour (7)
I believe the answer is:
kindred
'similar' is the definition.
('kindred' can be similar in meaning to 'similar')
'type and colour' is the wordplay.
'type' becomes 'kind' (I've seen this before).
'and' says to put letters next to each other.
'colour' becomes 'red' (red is a kind of colour).
'kind'+'red'='KINDRED'
(Other definitions for kindred that I've seen before include "Closely related" , "Family and relations" , "Family - similar" , "Affinity" , "Related (people)" .)
