We propose a new technique to automatically assign visually distinct colors to streamlines bundles. Our technique takes into account spatial positioning of bundles to avoid assigning similar colors to neighboring bundles. This will help researchers visually disambiguate close bundles. We show that basic techniques simply trying to spread the colors through the available spectrum often fail to take neighbors into consideration, and assign visually indistinguishable colors to close bundles. Our technique is fully automatic and stable, giving the same color assignments for any subject with the same bundles and similar structure.
