Options for strictly black (#000000) and white (#ffffff)

I’m designing a little game or a black and white 32x32 pixel display and I was wondering if there’s a way to set everythign to just black and white, instead of grayscale.

RGBA or Indexed Mode, just have B/W and delete all other colors/new palette

Ah thanks! Could you tell me how I can delete other colors or make a new palette?

Click and drag through colors on the palette, and right click and there should be an option to remove them. I think (I might be wrong) Under Image>Color Mode> you can change the mode. And I believe new palettes can be made with the pencil icon above the palette UI. I’m doing this from a chromebook, so I can’t check
