Microsoft's New Office Theme

Microsoft recently rolled out a brand-new theme for its Office products, and—woah!—purple has entered the building!

New colors fonts and more in Office theme

Flexing some vibrant new colors and styles, this new theme provides a fresh new look for not only Excel but PowerPoint, Word, and the other Office programs as well. Let me showcase some of the differences.

A Refreshed Color Palette

Take a look at this comparison between the old (2013-2022) color palette and the new one. You'll notice that yellow goes away, purple is on the scene, and the muted tones of many of the colors are replaced with more vibrant hues.

Table Styles

Another noticeable place you'll see the color changes is in the Table Styles menu.

New Fonts

In addition to new colors, there are also new font options. You're sure to notice that the default font for cells changes from Calibri to Aptos Narrow. While these fonts are similar, there are subtle differences such as the serif on the lowercase L to better differentiate it from the uppercase I. You can see what I mean in the word “Illustration” in the image below.

The letters of Aptos Narrow are slightly taller than Calibri, and the overall impression of the new font is a little more crisp, defined, and easier to read, in my opinion.

Default Line Widths

Another subtle change is the default thickness of lines on shape borders and arrows. You can see below how the width of the lines is more prominent, making them more noticeable.

Migrating to the New Theme

If you're liking these new changes, you can migrate to the new theme.

Your existing Excel files will not automatically update to the new theme. If you want them to change, you will have to do that manually.

Changing the theme is easy. On the Page Layout tab, go to the Themes menu.

Themes Option on Page Layout tab

The new theme is simply called “Office,” and the old theme is now called “Office 2013-2022.”

When you update to the new themes, you'll notice instant changes to your colors. I personally think the most drastic is the change from blue to purple.

Reverting to the Old Theme

If you hate the new changes, you do have the option of changing the default theme back to what you're used to. The process is different depending on what Office program you are using.


In PowerPoint, you can go to the Design tab and hit the drop-down button to see the menu of themes available to you. Just select the one that says “Office 2013-2022.”

This only changes the existing file that you are in. To make it the default for all of your new files, just right-click on the old Office theme, and select Set as Default Theme.

The process is similar in Microsoft Word. Go to the Design tab and select the old Office theme from the menu.

Once you have changed the theme to the old one, click the button on the Ribbon that says Set as Default.

Unfortunately, setting the old theme as the default in Excel is way more complicated. It involves saving a blank workbook with the old theme as an .xltx template file and then placing that file in the XLSTART folder on your computer. Then you have to create a new workbook using Ctrl + N on the keyboard because navigating to File and then New with your mouse won't work!

To me, this seems like an important fix that needs to be made before the new theme is rolled out to all users. We'll see if that happens.

If you would benefit from a step-by-step video showing you the process I just described, leave a comment and let me know. If there's enough interest, I will create a tutorial.

A Shortcut for Using the New Theme

Personally, I plan to use the new theme across all Office programs. As the new theme rolls out to the masses, there will be a transition time when you'll be copying and pasting between old and new, and vice versa, and you may want to change themes back and forth fairly frequently.

For that reason, I recommend you add Themes to your Quick Access Toolbar so that you can make those changes easily.

To add it, just right-click on the Themes option and select Add to Quick Access Toolbar.

Add to Quick Access Toolbar

Once Themes is added to your Quick Access Toolbar, you'll be able to make the change instantly, no matter what Ribbon tab you are on.

Power Query and Pivot Tables

The Power Query output will still be green in the new Office theme, just a more vivid hue:

And Pivot Tables will default to a more vibrant blue:

You might also notice with Pivot Tables that if you switch from the new theme to the old theme, the column sizes change slightly, so you might have to adjust the column width if you see any ###### going on.

Your Impressions?

This new theme has not been rolled out to all users yet, and I'm not sure of the timing for when that will happen. You can stay updated on that by following the Microsoft blog. In the meantime, I'd love to hear what you think of the new theme. Do you love it? Do you hate it? Leave a comment with your thoughts about it—or any questions you may have. We love hearing from you.

  • Overall, it is better with more bright colors and thicker border lines. BUT I would argue that we don’t need 2 greens and 2 blues. I would suggest removing the dark green and replacing it with the old yellow/yellow orange, and also getting rid of the dark blue and replacing it with the old grey. Basing this on color theory, there is a lot of connotation with the use of yellow (as cautionary) and also of grey (to hide, represent as old information), so getting rid of those as initial selections is not actually a time saver. I do like the purple as it adds another different color selection option. Obviously, you can select any color you wish under “More Colors” so it isn’t really a huge issue, but will probably be more of a minor hindrance removing those colors than a minor help. In my eyes, it’s an unnecessary change and the time in developing could have been used for bigger/more important things, but I do support the notion of continuous improvement.

  • Interesting. My “test” word, relative to fonts, is “IlLINO1S-0123.” Noto Sans lets me clearly see the different characters.

  • Thanks for the message, John.
    The addition of purple is welcome, though a milder shade would have been pleasanter to work with.
    It seems to me that having 3 similar shades of blue and 2 similar shades of green is absurd, just as losing my favourite (yellow, excellent for gentle highlighting) is a great shame. Why not include red or a coffee/tea brown?
    Mild colours/tints are generally more relaxing to the eye and therefore easier to work with. Vivid ones may be better for users with lower visibility, such as suffering from cataracts (as I used to).

  • Hi John,
    Well, I cannot say I hate the new theme or love it.
    I think this is all in the eye(s) of the beholder and what feelings the data needs to display.
    I’m still happy with Office 2021 so … let’s keep it like that for now,

  • Oh, my! They do seem a bit garish, if I’m honest.
    I really love the old theme but over time could grow to love some of the new theme. Love purple, but only on fabrics!
