How to remove automatic yellow highlighting for text in iOS Notes

Hello rags34,

Let's clarify a few details so we can go over this together. Currently, Notes on iOS doesn't have any option to change the color of the text.

The article below can help:

Use Notes on your iPhone, iPad, and iPod touch

Where did you sync your Notes from? If you have a Mac that you sync with, you can change colors and formats on the Mac using Notes and have it sync with your iOS device: Write and format notes on Mac

"Format text

You can apply a style—such as heading or body—to quickly format a paragraph.

Note: To use paragraph styles, you must be using upgraded iCloud notes or notes stored on your Mac.

1. In the Notes app  on your Mac, click a note in the notes list or double-click a note in gallery view.
2. To format text, do any of the following:

• • Change the formatting of selected text (such as changing a phrase to bold): Select some text, click the Format button , then choose an option (or use the Touch Bar).
  • Change text alignment: Click anywhere in the text you want to change, choose Format > Text, then choose an option.
  • Change text font, color, size, and more: Select the text you want to change, Control-click the selection, choose Font > Show Fonts, then use the Fonts window to make changes."

We hope this helps.

Cheers.
