Why does the color not show on some pages?

Scanned pages are a single picture of the paper, and the picture covers the whole page — including the background. The color shows on pages with real text.

Which color is easiest to read?

Many readers find a soft cream or pale blue easier on the eyes than bright white for long reading. Pale colors also print well; a dark background uses a lot of ink.

Can I remove the background later?

Keep the original file. The color is added as its own layer behind the page, so the original is the easiest way back.
