Why is my pages document changed from black letters to yellow

Hi wmbeak,

It's possible you changed the text formatting. Visit Change how text looks in Pages on Mac, iPhone, or iPad to learn how to make these changes:

"Change the color of text

1. Select the text.
2. Click the Format button  in the toolbar.
3. Click the Style button in the sidebar. If the text is in a text box, table, or shape, first click the Text tab at the top of the sidebar, then click the Style button.
4. Click the pop-up menu below the Font section, choose Text Color, then choose an option to pick your color:

• To pick a color that coordinates with your template, click the color well, then choose a color.
• To pick any color, click the color wheel, then choose a color from one of the color palettes."

Regards.
