For molecular modelers, visual clarity is key to unraveling the secrets of complex molecular systems. However, achieving a well-structured and meaningful visual representation can often be a challenge. SAMSON, the integrative molecular design platform, offers a powerful feature to address this: the ability to apply customizable color schemes to structural and visual data, enabling better insight and communication of molecular information.
What are Color Schemes in SAMSON?
In SAMSON, color schemes simplify visualizing molecular structures by applying colors based on user-defined criteria. These schemes can be applied to visual models, meshes, labels, and nodes (atoms, residues, etc.). Colors improve perceptibility, helping researchers quickly grasp molecular patterns—like chain IDs, residue properties, or even temperature factors.
Choosing and Applying Color Schemes
Applying color schemes in SAMSON is straightforward. Users can apply predefined schemes manually or via the Inspector. Let’s explore two examples:
- Constant Colors: Assign a single, uniform color to selected molecules or nodes. This is ideal when highlighting specific elements in a system for presentations or educational use. A simple dialog lets you pick your preferred color, and the result is applied uniformly as shown below:

- Attribute-Driven Colors: For more advanced visualizations, you can apply colors based on specific node properties. For instance, residues can be colorized based on their hydrophobicity:
In this example, residues are colorized to emphasize hydrophobicity. This can instantly guide structural biologists in analyzing surface properties of proteins.
Customizing Color Schemes
To address specific analysis needs, SAMSON also allows full customization of color schemes and color palettes. Custom palettes can use different color spaces—including HCL palettes designed for better human perception. Fine-tune palettes by manually adjusting parameters, reversing gradient direction, or even designing new palettes. Users can save their palettes locally for future use.

How to Manage Material Appearance
Materials in SAMSON combine color schemes with additional visual properties like metallicity or roughness. Using the Inspector, users can preview, adjust, and reset materials. You can even apply predefined appearance presets to achieve a polished, publication-ready look.
