Indigo for a chess computer (4,4)
I believe the answer is:
deep blue
This clue might be a double definition.
'indigo' is the first definition.
(indigo is a dark shade of blue)
'chess computer' is the second definition.
'deep blue' can be an answer for 'computer' (I've seen this before). I am unsure of the 'chess' bit.
'for a' is the link.
Can you help me to learn more?
(Another definition for deep blue that I've seen is " Computer".)
I've seen this clue in The Guardian.
Want a hint initially instead of a full solution?
