Depends what she is after, a DSLR is potentially an amazing tool but I would say you need to invest more money to make the most out of it, since to me the point of a DSLR is that you can swap lenses and use specialty glass (like a macro lens for small critters, a fast lens for portraits, etc.). I don't think it's worth the hassle and cost if you're not passionate about photography.
These days you can find great all-around bridge cameras that deliver good image quality at both wide and tele focal lengths, like Nikon's latest P900 or the cheaper Panasonic FZ200. If she'd like something more compact Sony's RX100 III has a very good reputation, and so does Canon's GX7. Here's an interesting round-up on high-end compact cameras:

I don't know whether you can adjust the colour before shooting but you can do it afterwards in the camera, whether you have a DSLR or a bridge (and I assume a compact) camera.
