> "Color is a fundamental attribute of these precious works of art, and we 
> particularly care for the most 'endangered colors,' the organic-based 
> pigments and dyes," she said. "To preserve manuscript illuminations for 
> future generations, we are combining methods from the humanities and the 
> natural sciences."
