Took this picture of a very red rose. I played with the light and white balance but keep getting a semi violet ting. What do I need to fix? Shooting a D3200 Tamron 60mm Macro lens at f22, .4 seconds ISO 200
What is your PP software? You could selectively play with the violet color channel. You could alter its luminance, saturation among other things.
Can we assume that the violet tint isn't visible to the naked eye? What sort of lighting was used? If the violet colour doesn't originate in the flower itself it must be due to a blue element in the light that's falling on the flower. If your eye doesn't see it it must be getting exaggerated by the camera or the optics, but it's unlikely that the camera is inventing it from scratch, especially since it's localised and not an overall tint. If it's outside, the sky will be the source of the blue tint, or if it's inside it has to be the lighting. In any case, PP should be able to mitigate it.

Well, in my opinion, two things going on.
1.) White balance. What do you mean you "played with the white balance"? Did you shoot a reference target before taking the picture and then setting the white balance to a custom WB? If not, that will help.
2.) Digital cameras have trouble with red. That's just the truth.
Your alternative is to just fix it as well as you can in your post processing software.
Red can be very difficult to get right in a digital camera especially with close up or macro, the problem doesn't seem to arise with distant red objects.
I have no answer, but it's still quite a nice image.
I would try to lower the saturation I am on cell phone or I would try for you Others could try. David
I understand your frustration. Digital cameras seem to have as much trouble with red as film did with purple! And printers intensify the problem! What seems to work for me is to work with adjusting the hue on the red slider and then increase the yellow a tad. Sometimes it work, sometimes not! I do that on the individual colours, not on the white balance setting.
I'm going to go out on a limb and say the problem is that the photo as shot was blown out (overexposed). It looks like you tried to correct that in post-processing because the histogram has nothing in the "whites" range and only a little (all red) in the "highlights" range. The prominent petals on the right look flat to me, which is where you've gone beyond the ability to recover any detail.
Counterintuitively, play around with magenta in HSL. First try amping up the luminance as far as you can: you'll find detail that is lost in red, and the blue tinge will go away.
In situations like this I use a custom white balance. My Nikons have trouble with purple and red; when I use the custom white balance the problem goes away. You have to remember to reset your white balance though!
I just remembered when shooting in a huge garden, I experimented a lot. I seemed to get better details and true colour in the reds when I underexposed about a third. Sometimes 2/3. It seemed to take out the oversaturation.
I reduced the blue, is this more like it.
