In molecular modeling, effectively visualizing complex structures is both an art and a science. One common pain point for modelers? Tailoring visuals to clearly highlight significant features. Whether you aim to compare datasets, emphasize structural regions, or prepare presentations, SAMSON’s robust color palette system offers an invaluable solution: the ability to create and customize your own color palettes.
Why Custom Color Palettes?
While SAMSON provides a rich library of default palettes, sometimes your project calls for something more specific. Custom color palettes allow you to:
- Represent your data in a way that aligns with your research goals, such as using a specific brand or journal-compliant color scheme.
- Improve visual clarity for complex models by crafting palettes with increased contrast or distinct shades.
- Revolve around accessibility, e.g., ensuring your visualizations are color-blind friendly.
How to Get Started
To add or create custom color palettes in SAMSON, follow these steps:
- Access Palette Customization: In SAMSON, navigate to the color palette dialog. You can find this under colorization workflows. This is your central hub to manage existing palettes and add your own.
- Create Your Palette: Select the option to add a new palette. Use HCL (Hue-Chroma-Luminance) color definitions to build a palette from the ground up. HCL is beneficial for perceptually uniform palettes that ensure consistent step changes in color intensity.
- Save Your Palette: Once your colors are finalized, save the palette for future workflows. You can also name it for easy reference in future sessions.
- Test It Out: Apply your new palette to molecular structures to confirm its effectiveness. Modify it further as needed for optimal contrast and clarity.
Here’s a helpful tip: In the color palette dialog, you can revert the left and right arms of existing palettes for additional flexibility.
Why HCL Matters
The HCL (Hue-Chroma-Luminance) color space is a fantastic tool for creating palettes tailored to human perception. By focusing on chromatic transitions and luminance shifts, HCL ensures smoother gradient experiences and avoids misleading intensity patterns. This is especially crucial when emphasizing structural highlights or presenting results to a diverse audience.
An Example Worth Noting
Below is an example application of a custom color palette:
- Goal: Distinguish between hydrophobic and polar regions in a protein structure.
- Solution: Use a diverging HCL palette such as Red2Blue, or better yet, create your own diverging palette with customized gradients for enhanced contrast.
Your custom palette can then be easily carried over to other similar workflows or structures, saving time and maintaining consistent visuals for publications or presentations.
