No, those are both 29b (red lilac). 29b has a distinct greyish cast, similar to 29, but is perf 11.5x12, instead of perf 12, that's the easiest way to tell it from 29.
Some scans below (typical caveat of shades with my scanner, etc.). If those aren't distinct enough, I can pull some others for reference.
