Double Duty

This concept of one line being two separate constraints is new to me. I tried to make it fun and approachable.

Rules:

Normal sudoku rules apply Clues outside the grid sum up the digits along such diagonal, digits may repeat if allowed by other rules. Yellow lines are German whispers AND a between line. Blue lines are a palindrome AND a pair of German whisper line. (i.e. 928 829 is a valid blue line) Both criteria must be met.
