How do I correct this

I have what looks like CA in the attached screenshot. This is a 100% crop from a 40 with a 35-90. It is of sunlit water from a distance of a few hundred metres looking straight down. I've never seen it before. Can Phocus fix it  or is it a PS cloning job?

Jeff,

In PS Hue/Saturation or Phocus Color Correction, select purple color and desaturate it, adjust the effect parameters to get the exact color that is bothering you.

If there is any purple in the frame that you would like to keep, than it's better to do it in PS and draw in the mask that would include only the parts where you want purple to be removed.
You can also shift it into blue with Hue in PS prior to desaturation to get better results.

Thanks Alex. I was cleaning it up and almost fell off my chair. I've never seen anything that Phocus couldn't fix before before.
