A list of flurochromes, together with their excitation and emission spectra is available at the Invitrogen/Molecular Probes website. This website can also be used to examine the compatibility of multiple fluorochromes as illustrated in the example provided below for DAPI, Alexa Fluro-488,-494, and -633.

Brief tutorials are available at http://probes.invitrogen.com/resources/education and individual spectra may be viewed and compared at http://probes.invitrogen.com/servlets/spectra.
