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.

Page background

Put a color, a letterhead or a faint logo behind every page, without covering the text.

Before you start

Once the file is in, a preview shows your first page with the background — the text always stays on top.
Light colors read best; for a logo, lower the opacity so it sits quietly behind the text.
Letterhead? Use Image and Fill the page so it covers the sheet edge to edge.

How to do it

Add your file
Add the PDF you want to color — a handout, a long report you read on screen, or slides for print.
Set it up the way you want
Pick a soft color, or an image such as your letterhead, with its placement and opacity. The preview shows the first page, and you choose all pages or only some.
Download the result
Download the PDF. The color sits behind everything already on the page, so text, images and links stay exactly as they were.
