The posted pic looks like an old colour slide from someone's '50s holiday snapshots......
Those early colour processes weren't particularly stable. By now the blue dyes may have faded, leaving a magenta cast to the image, very noticeable in a lot of old colour slides and 8 mm movie film.
I've never bothered with movies, but if the software is anything like Photoshop etc. I'd have thought you would be able to colour correct it to at least some extent by adding blue and cutting back the magenta.
