Color settings in Notes app

So when I'm using the notes application, I decided to change the font and noticed the color could be changed from the Format > Font > Show Font menu. However, it also allowed me to select another color setting as well and when I enable the "show preview" option, the text is an orange color that I selected, and then the background a green. When I exit the Font option's window, and start typing it was with my new font in the color selection I chose, but the page color was unchanged. I reopened the Font menu and now it no longer allows me to change the green color (which appeared to be a color option to change the page, even though I've read online that you cannot change the page color in notes).

Does anyone know what the other color option is or how to make it available to edit again?
