Microsoft’s Red Gets a Makeover. Here’s Why It Matters for Accessibility

Microsoft 365 quietly updated its standard red font color to improve readability and meet accessibility standards. This small change makes a big difference, and you can apply it manually too.

Ever struggled to read red text on a white slide? 

You’re not the only one. 

For years, Microsoft’s default red, used to emphasize, alert, and annotate, has been visually loud but not always legible. 

Especially for folks with low vision or color sensitivity, that bright red could be more of a barrier than a beacon. 

Here's a Cool Tip:  Microsoft Has Adjusted the Default Red in Microsoft 365 Apps.

It’s a subtle shift, but it speaks to a broader push for inclusive design.

What Changed and Why It Matters

Microsoft 365’s standard red, previously set to RGB 255,0,0, has been darkened slightly to RGB 238,0,0. 

That tweak helps the color meet Web Content Accessibility Guidelines (WCAG) for contrast against white backgrounds. 

The updated red now passes accessibility checks, making it easier to read in Word, PowerPoint, Outlook, and OneNote across Windows and Mac.

This isn’t just about compliance. 

It’s about clarity. 

Whether you're flagging an urgent email, marking up a document, or building a presentation, the new red helps ensure your message gets through to everyone.

What You'll Gain

• Better readability for all users 
• WCAG-compliant contrast for red text 
• Works across Microsoft 365 apps without extra setup

Step-by-Step Instructions

Here's how to do it.

Microsoft Web/Desktop (Windows & Mac)

If your app version hasn't updated or if you are using an app like Microsoft Word, here's how to change the color manually:

1. Open Word, PowerPoint, Outlook, or OneNote.
2. Highlight the text you want to color.
3. Go to the Home tab → Font Color.
4. Select the red under “Standard Colors.”
5. Confirm accessibility using the Review tab → Accessibility Assistant.
