Main Display on load in

[Merlin5523]

I need some help please. I am having a problem with display color once loaded in. My display is yellow like night vision is turned on but it isn't. If I turn that on the yellow just gets brighter and I can't find a way to get my display back to normal color. This happened when I was fighting a mob in the new zone about a week ago and I haven't found a way to get it back to normal. This seems to only effect one toon and none of my other toons. Can anyone help with this?
