One Five Nein

Rules:
- Normal sudoku rules apply: Place the digits 1-9 once each in every row, column, and 3x3 box.
- Indexers: Digits placed in red cells indicate the position of the corresponding column number in that row.
- Two Truths and a Lie: Out of the three columns containing red cells, exactly two of those columns contain only true clues, and the other contains only false clues. In other words, for exactly one of columns 1, 5, and 9, all of the red cells in that column must not be valid indexers.

Love two truths and a lie, never seen it with 159 before and it worked really well. Thanks!
