Samyang 8mm fisheye purple cast

Took a few test photos this AM. Part of this was a self inflicted problem brought on by a frenzy of button stabbing and wheel spinning. I discovered the AWB had been moved off it's setting to the custom setting. Apparently the custom white balance without corrective input created a lot of the purple cast. I corrected and the results you see here. Still very sensitive to any light coming in from the edges of the frame. I probably should create a custom color balance I like and switch to it when using this lens.
