The harmony of the visuals in your PowerPoint
You don't mix tea towels and napkins, but you can mix visuals!

Harmony represents one of the essential pillars of information design, encompassing the harmonization of fonts, color associations, and any other graphical features within any visual interface. It makes it possible to enforce the visual identity of a brand and to improve communication media.
At the heart of this quest for visual balance are illustrations. While it is undeniable that the use of illustrations is fundamental to slide design, it is crucial to recognize that their full power comes into being when slides are designed. share a link and a graphic linearity. This graphic synergy between illustrations enriches visual communication and gives visual coherence to your presentations, thus captivating your audience in an even more powerful way. Let's discover together how this visual harmony can transform the impact of your presentation designs.

To begin our exploration, let's quickly clarify the concept of illustration. This term encompasses three main forms in the context of presentations:
- In the sense of visuals/images
- In the sense of illustrated sketches
- In the sense of pictograms
Understanding these different forms of illustration is the starting point for optimizing the visual impact of your slides. With these options in mind, the next step is to find the right resources and use a consistent style to illustrate multiple concepts in your presentation. The objective is to create harmonious visuals that are part of the same visual universe.
1 - Harmonization of visuals/images
Harmonizing images in a PowerPoint presentation is a key element in creating a consistent and professional appearance. The images used in a presentation can have a significant impact on audience engagement and message understanding, which is why it is important to build a clear visual unit.
First of all, it is important to choose a consistent visual style for all images in the presentation. This may include using similar filters, colors, or styles for all images. Next, we recommend using frames and borders to frame images and create a consistent appearance. Frames and borders can be customized to match the look and feel of your presentation.
Another way to harmonize images is to use visual effects such as drop shadow, reflection, or brightness to create a cohesive appearance. These effects can be applied to all images in the presentation to create visual unity. It is also important to consider the size and resolution of the images used in the presentation to ensure optimal image quality. Images should be resized consistently to fit the layout of the presentation.
The image banks that we recommend
When it comes to images, avoid Google Images and photos with the Shutterstock filter.
Instead, choose free banks such as unsplash.com or Pexels.com, offering quality photos in free access. Even if the images selected are of high quality, add a filter to create visual unity.
A little tip for customizing images and integrating your text into them:
1- Create a shape
2- Adjust its fill color
3- Apply transparency to let the photo appear
4- Apply this approach to all the photos in your presentation.

By following this process, writing on a photo has never been easier.
2 - The illustrated sketches
An exciting alternative for bringing your ideas and concepts to life in a presentation is The use of skits. These visual mini-dramas place characters in a variety of work scenarios, whether it's a business meeting, a data calculation, or the presentation of a strategy. This approach offers a refreshing and modern design, making it possible to avoid the overexploitation of “corpo” visuals that are sometimes too conventional.
When opting for the use of sketches, make sure to create or use illustrations from the same illustrator. This artistic coherence contributes to the visual harmony and overall aesthetics of your presentation. For this purpose, the mprez® agency offers a free PowerPoint template and ready to use. The latter is full of numerous illustrations that will illuminate your slides dedicated to the world of business and enterprise.

3 - The pictograms
Pictograms remain essential when it comes to to illustrate your PowerPoint slides. Their use is not only a current trend, but it remains and will remain an excellent way to offer clear visual references, thus structuring your slides and easily reinforcing your concepts. Pictograms simplify explanations, make it easier to remember, and improve the overall design of your presentation.
Integrate them without restriction
Do not hesitate to integrate these small graphic elements without counting. Their power lies in theTheir ability to simplify complex ideas. Pictograms are reliable visual companions, allowing you to deliver your messages in a concise and compelling manner.

Use them simplifies your presentation and makes it lighter, making it much easier to read.
Opt for the SVG format
Valuable advice: Always include pictograms in SVG format in your presentations. This tip gives you the freedom to customize the color according to your needs, thus bringing a personalized touch to your creation. This aspect is essential to integrate all your elements into your graphic charter, thus strengthening your brand image and the coherence of your visuals.
