When I create my templates, I try to use ‘Theme colors’ 99% of the time. I do this, in order for you to customize each deck with the colors you like the most. You don’t have to settle for the colors I have chosen, the sky is the limit.
So now, what do I mean when on the description of my templates I say “I’m using theme colors” or “you can edit the theme colors”? Here is a step by step guide for Google Slides and PowerPoint.
How do I change the theme colors in Google Slides?
Click on Slide > Edit Theme (formerly known as Master)

Click on ‘Colors’.

You’ll see that a panel on the right opens up.

Click on ‘Choose a theme color’ and select any of the colors on the dropdown.

Here you will be able to type / paste an HEX code (if you are not sure which color palette to use, you can check out Coolors and get the HEX codes there). Or you can select any of the default colors given by Google Slides.

Repeat this step for every theme color. Once done, close the master (theme) and that’s all!
Your deck will have a new look and feel with just a few clicks!

How do I change the theme colors in PowerPoint?
Click on View > Slide Master

Click on ‘Colors’ and a dropdown will open. Here you can choose whether to use one of the color palettes given by Microsoft (Office, Office 2007 – 2010, Blue, Green, etc.) or use your own custom colors (Customize Colors…)

If you choose to use one the palettes that come with ppt, simple scroll and move your mouse on top of each to see a “preview”. Once you have decided the one you like the most, simply click on it.
Close the Master View and done!

Now, if you choose to use your own custom color palette, click on Colors and Select ‘Customize Colors…’ a popup window will open.

Click on any of the theme colors, and a menu will open. Here you can choose to change it for any of the given theme colors, any of the Standard Colors, or any color you like. To access this last option click on ‘More Colors…’

Here you will be able to choose between Standard or Custom. If you choose ‘Standard’ simply click on the color you like and click OK, and if you choose ‘Custom’ you can select any of the colors and a specific shade, or use the RGB selectors or type / paste an HEX code. When you are done, click OK.

Repeat this for every color you want to change. Once done, close the master view, and you are all set!
