Where to modify background/font palette?

[ti-r2]

I noticed the font PNG has 5 indexed colors, of multiple shades of gray, and if I try to use multiple shades in the letters they do show up after compiling. However, when I change the palette in the font file, it still reverts to shades of gray. Is there a way to set the font palette so I could use multiple colors on my font file?
Similarly, where in code is the background color of the text box set, and is there a way to easily change it?

The problem is that the font and the cursor share the same palette; whichever of the two that's called last, will be the one used. You could try to move the font declaration to happen after the cursor declaration
