Further to the right, further down (5)

I believe the answer is:
bluer
'further down' is the definition.
(I've seen this in another clue)
'further to the right' is the wordplay.
'further' becomes 'blue' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'to the right' becomes 'r' (common abbreviation).
'blue'+'r'='BLUER'
Can you help me to learn more?
(Other definitions for bluer that I've seen before include "more despondent" , "getting more down" , "more depressed" , "More conservative" , "Less cloudy (sky)" .)
