Can I apply these styles to entire dashboards or just individual plots?

Both. The skill provides patterns for individual HoloViews plot customization as well as global Panel theme configurations that apply to entire web applications.

What Python libraries do I need to use this skill?

You will need colorcet, holoviews, panel, and bokeh installed in your environment to utilize the full styling and colormap capabilities.

What are the benefits of using Colorcet over standard colormaps?

Colorcet colormaps are perceptually uniform, meaning the perceived change in color is proportional to the change in data value. This prevents visual artifacts and misleading interpretations common in maps like 'jet' or 'rainbow'.

How does this skill help with accessibility?

It provides specific implementation patterns for colorblind-safe palettes (e.g., cet_d4, cet_p3) and grayscale-compatible maps to ensure visualizations are interpretable by all users.
