This is a really useful database on a wide range of pigments. It is in Spanish (Base de datos de pigmentos), and you have to apply for a password to get excess.  Once you have a password, you can freely get access to the database. You can search on names or chemical elements. You can also search on observed features in a spectrum or color coordinates, to see what pigments match your data. For every pigment you find the chemical formula, adescription, the color coordinates, XRD spectrum, Raman spectra and an FTIR spectrum.

The NIST (National Institute of Standards and Technology) website contains a wide range of databases. Some of them can be accessed freely, others can be ordered. On-line databases can be found on: www.nist.gov/srd/online.htm. You can freely access the Chemical Webbook at webbook.nist.gov/chemistry, and the atomic spectra database at physics.nist.gov/cgi-bin/AtData/main_asd. 

 

http://www.chim.unifi.it/raman/pfcnr_pig.html 

This site is from the University of Florence, Department of Chemistry and has free access. It gives microRamanspectra of 39 pigments and IR spectra of 11 pigments. A database with spectra of different binding media is under construction.

 

http://www.irug.org/database.html

This website from the Infrared and Raman User Group contains over 1000 IR spectra of oils, waxes, natural and synthetic resins, pigments, proteins, gums, dyes and natural minerals. It is available only to IRUG individuals and/or their institutions in the non-profit sector, who contribute 10 or more accepted spectra to the compilation. The contact person for IRUG in Europe is Boris Pretzel from the Victoria&Albert Museum in London.
