When dealing with complex molecular models, clearly annotating and visualizing specific features can greatly enhance understanding and communication. Labels serve as a way to add contextual information, highlight structural details, or make presentations easier to follow. In this post, we’ll explore practical steps for customizing labels in SAMSON, a molecular design platform, to maximize their impact.
Why Labels Matter
Labels in SAMSON can provide important information like node names, measurements, or descriptions of larger structures. They ensure clarity in crowded scenes, such as when showing atoms, residues, or entire molecules. However, a key question many modelers face is: How do I make these labels stand out in just the right way?
How to Adjust Font Settings
One of the simplest ways to enhance your model is by customizing the font of your labels. SAMSON provides flexible options to modify label fonts either globally or specifically for individual annotations. Here’s a quick guide:
- To adjust fonts globally, open Preferences > Rendering > Labels. You’ll also be able to modify the number of decimal places for labels showing distances and angles, perfect for precision-driven tasks.
- If you want to change fonts for specific labels, select the desired labels and open the Inspector. Use the Choose font… option to update fonts for the last selected label or for all selected ones if “Edit all selected nodes” is activated.
- Need a reset? Simply double-click on the Font option in the Inspector to revert labels to the global default.

How to Fine-Tune Label Colors
Color not only adds vibrancy but can also serve a functional purpose like grouping related nodes or highlighting specific features. Here’s how you can manipulate label colors:
- Select a label in the Document view or the Viewport and use Color > Constant to choose a color from the pop-up dialog.
- If you prefer modifying colors through the Inspector, select the label and click on Color > Constant.
- Reset the color at any time via the Inspector by clicking the X button (clear icon).
Below is an example of how the color adjustment process looks:

Transparency Settings
Transparency can be modified for labels in the Inspector, which is especially useful for focusing attention without overcrowding the scene.
Why Customization Enhances Your Work
By customizing label fonts, colors, and transparency, molecular modelers can focus more efficiently during analysis, highlight key findings during presentations, or create clearer publication-quality images. This level of control ensures that labels provide relevant context without overwhelming your molecular scenes.
Labels can be an overlooked feature, but they are indispensable tools to effectively communicate your findings.
