Try these...

Data in the range A2:C6

E2 = Red

Formula in F2 array entered** for the max date:

=MAX(IF(C2:C6=E2,B2:B6))

Formula in G2 array entered** for the code:

=INDEX(A2:A6,MATCH(1,IF(C2:C6=E2,IF(B2:B6=F2,1)),0 ))

** array formulas need to be entered using the key combination of
CTRL,SHIFT,ENTER (not just ENTER). Hold down both the CTRL key and the SHIFT
key then hit ENTER.

1002 4/1/05 Red
1003 8/1/09 Blue
1004 9/1/08 Blue
