I was wondering about the physics of color, and now am interested in finding out if there are any resources (databases, text files, html tables, or pdf listings) of species and their associated colors or (ideally) color wavelength spectrum.
For example, a rose bush might have a pink (flower) color spectrum and a green (leaf) and brown (stem) color spectrum. A worm might have a brown and pink color spectrum. A lion might have a yellow and brown and gold color spectrum. Wondering (a) if any of this information is captured in any form on the web (such as 1 journal article per species), and (b) if it is aggregated into a database, text file, table, or other sort of list which includes lots of species (animals, plants, fungi, rocks, etc.), so it would say the wavelength of visible light that it emits, or some ranges of it, or even a hex color range.
