FilterMeister has a vast range of predefined colors from many popular colorspaces but sadly enough, the included manuals do not show them, that is where this handy resource comes in; a list off all available predefined colors and colorspaces with nice colored boxes showing what they look like. - Mixing modes
This page contains a list of how to implement PhotoShop's' mixing modes into your own FilterMeister plugins, nearly all mixing modes can be found here and all have been tested thoroughly.
