Magenta filter for Hero4 Black?

[decapoddiver]

I had one for the Hero3 Silver and it made a huge difference but my wife surprised me yesterday with a 4 Black. Based on what I'm reading, the black color-corrects pretty well. Do any 4 black owners here use the magenta or have an opinion? Thanks.

I've used the GoPro Magenta filter on my GoPro 4 Silver in the green water at Dutch Springs and it seems to do a pretty good job. This is the press-on filter from the GoPro web site.
