One common challenge faced by molecular modelers is the need for clear and effective visual differentiation in complex molecular systems. Whether you’re visualizing macromolecules, comparing properties across different structures, or emphasizing specific regions of interest, choosing the right color palette can dramatically impact your workflow effectiveness. Luckily, SAMSON makes this easier with its customizable color palette options.
Why Adjusting Color Palettes Matters
Molecular models often include intricate details and datasets that need to be visually deciphered quickly. Default color palettes don’t always cater to every project’s unique requirements, especially in workflows involving large datasets, overlapping regions, or comparisons. The ability to tweak existing palettes or create entirely new ones can make a significant difference in how molecular insights emerge during analysis.
Reversing Palette Gradients
One handy feature SAMSON offers is the ability to reverse the arms of diverging or sequential HCL color palettes directly within the color palette or color scheme dialogs. This is particularly useful when the default gradient flow does not align with the structure or property mappings you want to highlight. For example, flipping a Red-Yellow gradient might help spotlight lower-energy regions in your model, depending on the desired interpretation.
Creating Custom Palettes
If the default color palettes don’t fully meet your needs, SAMSON also allows you to design your own custom palettes. This flexibility is invaluable for tailoring visualizations to specific datasets or presentation styles. To define a custom palette:
- Open the relevant color scheme dialog in SAMSON.
- Choose the ‘Create New Palette’ option.
- Select colors that align with your desired gradient or discrete segmentation.
- Save the palette for consistent use across your visualizations.
Tip: When creating custom palettes, ensure high contrast between adjacent colors for clarity, particularly in discrete or categorical data visualizations.
Examples of Predefined Palettes for Inspiration
Not sure where to begin? SAMSON provides numerous predefined color palettes that you can use directly or as foundations for your customizations. Below are a few examples:
- Discrete palettes such as ‘Carto Vivid’ and ‘Set2’ for categorical data.
- Sequential palettes like ‘Blue-Green-Yellow’ for property gradients.
- Diverging palettes such as ‘Berlin’ and ‘Blue-Red’ for highlighting midpoints in data distributions.
