iPhone does not have a built-in setting to change all text color across the system, but you can change text color in specific apps and in accessibility features that affect how text appears on your screen.

If you want to change the color of text you are reading or writing, your options depend on which app you are using. Mail, Notes, Messages, and other built-in apps each handle text color differently — some let you change it, some do not. If you are looking to change how text appears everywhere on your phone for readability, you can use accessibility settings like Smart Invert or Color Filters instead.

This guide covers where text color controls actually live on iPhone, which apps support them, and how to use accessibility features if you want to adjust text appearance across multiple apps at once.

Key Takeaways

  • Most built-in iPhone apps do not let you change text color, but Mail and Notes have limited color options in specific contexts.
  • Smart Invert and Color Filters in Settings > Accessibility can change how text appears across your entire phone without affecting individual apps.
  • Third-party apps like Word, Google Docs, and Canva have their own text color tools that work independently of iPhone settings.
  • If you want to change text color in Messages, you can only do so by using emoji reactions or text effects, not by changing the font color itself.

Changing Text Color in Mail

Mail on iPhone does not let you change the color of text you are composing in the main message body. However, you can format text using bold, italic, and underline by selecting text and tapping the formatting menu. To access this, select the text you want to format, tap the arrow next to BIU (bold, italic, underline), and choose your option.

If you want colored text in an email, your best option is to compose the message in a third-party app like Google Docs or Microsoft Word, format it there with color, and then copy it into Mail. Some email clients like Gmail (accessed through Safari or the Gmail app) offer more formatting options than the built-in Mail app.

Changing Text Color in Notes

The Notes app does not have a text color feature. You can use bold, italic, underline, strikethrough, and monospace formatting by selecting text and tapping the formatting menu, but you cannot change the color of individual words or paragraphs.

If you need colored text in a note, create the note in a different app first. Google Keep, Microsoft OneNote, and Notion all run on iPhone and support text color. You can also take a screenshot of colored text from another app and paste it into Notes as an image.

Using Smart Invert to Change Text Appearance

Smart Invert reverses the colors on your screen while keeping images and photos looking normal. This makes text appear lighter on a darker background, which some people find easier to read. To turn it on, go to Settings > Accessibility > Display & Text Size, scroll down, and toggle Smart Invert on.

Smart Invert affects every app on your phone at once, including Mail, Messages, Safari, and third-party apps. You can turn it on and off quickly from Control Center by adding the Smart Invert toggle. Swipe down from the top right corner, tap the plus icon, search for Smart Invert, and add it to your Control Center.

Using Color Filters to Adjust Text Color

Color Filters let you explore a tint to your entire screen, which changes how text and other content appear. Go to Settings > Accessibility > Display & Text Size > Color Filters and toggle it on. You can choose from Grayscale, Red/Green, Blue/Yellow, or Monochrome, or create a custom filter by adjusting the hue and intensity sliders.

Color Filters work across all apps and can help if you find certain text colors hard to read. For example, the Blue/Yellow filter can make white text on a dark background appear more yellow, which some people find less straining. You can also add Color Filters to Control Center for quick access.

Changing Text Color in Third-Party Apps

Apps like Microsoft Word, Google Docs, Apple Pages, and Canva all have their own text color tools. In Word, select text, tap the paintbrush icon, and choose a color. In Google Docs, select text, tap the three dots, choose Text color, and pick from the palette. In Canva, tap the text, then tap the color swatch at the bottom of the screen.

These apps store your formatted text within their own files, so the color will appear when you open the document in that app or export it as a PDF or image. If you copy colored text from one of these apps and paste it into Mail or Notes, the color may not transfer because those apps do not support colored text in their native format.

Why iPhone Does Not Let You Change System Text Color

Apple designs iOS to use consistent text colors across the system for readability and accessibility. Black text on a white background (or white text on black in Dark Mode) is the standard because it meets contrast requirements for people with low vision. Allowing users to change text color globally could create combinations that are hard to read.

Instead of a system-wide text color setting, iPhone offers accessibility features like larger text, bold text, and color filters that adjust how content appears without breaking the design of individual apps. If you need text in a specific color for a document or project, use an app designed for that purpose — Word, Docs, or a design tool — rather than trying to change iPhone's system colors.

Frequently Asked Questions

Can I change the color of text in Messages?

No, you cannot change the text color of individual messages in the Messages app. You can add text effects like invisible ink or echo, but the text itself stays the color Apple sets. If you want to send a message with colored text, compose it in a notes or design app first, take a screenshot, and send that as an image.

Does Dark Mode change text color?

Yes. Dark Mode inverts the background from white to black and the text from black to white. To turn it on, go to Settings > Display & Brightness and select Dark. You can also set it to turn on automatically at sunset. Dark Mode affects all apps that support it, though some third-party apps may not follow your Dark Mode setting.

Will changing text color in Google Docs stay colored when I read it?

Yes. When you read a Google Docs document as a Word file or PDF, the text color is preserved. If you copy colored text from Google Docs and paste it into Mail or Notes on iPhone, the color may not transfer because those apps do not support colored text in their message format.

Can I make text a different color in Safari?

No, you cannot change the text color of web pages in Safari on iPhone. However, you can use Reader Mode to simplify the page layout, and you can use Color Filters in Settings > Accessibility to adjust how all colors appear on your screen, including text on web pages.
