How to provide reference images for custom icon requests

To help our team of Science Illustrators create accurate custom icons for you, we ask that you provide high-quality reference images. These references guide our illustrators and ensure your icon is both scientifically accurate and visually aligned with your needs.

Disclaimer: The fulfillment of icon requests is not guaranteed and depends on a variety of factors including subject matter prioritization, volume of requests, and complexity.

Who can request custom icons

Custom icon requests are only available to users on our Industry Team and Enterprise Plans.
For more details check out our Plan and Pricing page.

How many reference images should I provide?

We typically require 3–5 reference images per request, depending on complexity. More complex icons may require more references.

Our illustrators conduct their own research, but strong starting references help speed up the process and improve accuracy.

Types of reference images to include

To best support your request, we recommend including a variety of the following reference types:

1. Scientific diagrams – Diagrams from textbooks, scientific articles, or reputable sources.
2. Microscopy or imaging data – Real imagery that shows structures clearly.
3. Existing illustrations – Examples you like or want us to mimic (include source if applicable).

Qualities of a good reference image

Each reference image should be:

• Clear and legible – Details and labels should be easy to interpret.
• Scientifically accurate – From reputable and trustworthy sources.
• Oriented correctly – Show the desired viewpoint and all relevant structures.
