Tips to change background color


how to change that color which I drew on this pic? in book view mode
thank u

It looks like you are using Fixed Page UI (User Interface)
the canvas area you show is affected by a Settings> Advanced Option

just add
GradientColors #ff0000

like this

FixedPageUI [
GradientColors #ff0000
	TextColor = #000000
        ...

will add full red colour to all background canvas

you can add 2 or 3 colour gradients from start to finish of document
e.g. for blue to red to green it is GradientColors #0000ff #ff0000 #00ff00

or any mix you wish hexadecimal values are 00-ff for #RRGGBB

If you are referring to the background to change that color it is changed like this

FixedPageUI [
	TextColor = #000000
	BackgroundColor = #ff0000

thank u so much!!!
