How to match illustration colors to your slide design

Published: 10月 6, 2026

You add an illustration and it somehow looks out of place. Most of the time the culprit is color. Here is how to think about matching illustration colors to your design, and how to do it.

Why illustrations look out of place

Most documents use about three colors: one for text, one for the background and one accent (often the brand color). An illustration in yet another color stands out on its own and breaks the unity of the page. Mixing several colorful illustrations makes it worse.

Use colors your document already has, and the illustration becomes part of the design instead.

Start by choosing one line color

For illustrations made of lines and white shapes, decide the line color first:

• For a calm, neutral document: the same color as your body text (a dark gray close to black)
• To feel on-brand: your brand color or heading color
• To signal caution or emphasis: your accent color — but use it sparingly

For the inside (the white parts), keep white or use a very light tint of the line color for a refined look. On a colored background, choose “Transparent fill” so the background shows through.

Finding your brand color

The colors of your company logo or website are usually the brand colors. If your organization has design guidelines, they will list color codes such as “#BC1768.” You can type a color code straight into the color fields on FreeIconBazaar.

Giving several illustrations the same colors

When a document uses several illustrations, they should all share the same colors. Recoloring them one by one tends to produce slightly different shades.

1. On FreeIconBazaar, tick the illustrations you want in the list (up to 10)
2. Press “Recolor together” at the bottom of the screen
3. Set the line and fill colors and choose the formats (SVG, PNG)
4. Press “Download ZIP” to save them all in the same colors

The color code is part of each file name, so you can always tell which color you saved.

Common mistakes

• A different color for each illustration: color without meaning confuses readers
• Colors too close to the background: light lines on a light background are hard to see
• The accent color on every illustration: then nothing stands out where it matters

Summary

Pick illustration colors from the colors your document already uses. Choose one line color and apply it to every illustration — that alone transforms how consistent a document looks. For how to recolor in each app, see “How to recolor illustrations in PowerPoint, Google Slides and Canva.”
