Flash colour cast

[Nostromo]

I've got a yongnuo 685 and I've noticed that when i use it on white backgrounds (well it's much more noticeable on white) it seems to give off a purple/magenta colour cast. At first i thought it was because my subject had purple/red wine colour in it, so just thought it was a reflection off of that, but now i seen it in other shots aswell that don't have this colour in.
So my question is, is this normal and what is the easiest way to remove it from photos. I've got photoshop cc but am not that great with photoshop as i mainly use lr.

I sometimes see it too, and it's common to most speedlights, not just Yongnuo or Fuji - the light is often slightly purplish or pinky-blue, more so at low power outputs. I sometimes see it when bouncing on a white ceiling.

It's hardly noticeable TBH, but I fix it with a very mild wash-over of local colour correction in Lightroom - very easy.
