Background Color Issue

I’m trying to get all the backgrounds white. I can’t seem to get the left-hand pane to change from off white to white. Here’s a screenshot. Thanks!

How is “white” defined in your document?

Tinderbox symbolic colors like “white” or “darker red” can be set to different rendered colors in different documents. This lets you change the color scheme of a document without needing to set the color of every note. It also lets you say that, for this document, “white” is to have just a trace of mint, or a little bit of fall.

Worked, thanks very much
