I doubt that you could use amber LED's with VC paper, as it has yellow sensitivity, but I have been using red ones for years. You should test, of course, but I doubt that you will find a visibly red LED that fogs VC paper. If you want to do development by inspection of panchromatic film, use green LED's attenuated so you can just barely see by their light after you are dark adapted. BTW, red light least interferes with dark adaptation. If you want to do other things while film is in a closed tank and then inspect progress of development, use red light while working then switch to green for inspection.
