Setting Colors and Filament Manager

So I am trying to figure out a way to determine what I guess Hex Code or RGB value a certain Filament is. It’s not a Bambu color. Not sure if you folks know what a TD1 is but I built one for Hueforge. If I can get the hex code of my color can I enter that somewhere into BS so the color swatch looks right?
Also, I am trying to use the Filament Manager but see no way to tell Bambu Studio what roll I am using. if I go into the device tab and then click on a filament in the AMS I get the pull down to choose. In that list I see some filaments that are in my Filament Manger and a bunch that are listed as unsupported. Funny thing is some of the filaments I can choose are in the Generic category and Overture which are both non Bambu products. Any Ideas?
