I have a complete set of yellow Lee powder dippers, and have given up on finding a complete set of red ones. The only black ones I can remember seeing where meant to measure shot in the Lee Loaders from the mid seventies.
I did have a 12 ga Lee Loader that had an adjustable aluminum shot measure for a short time, but I never used it.
Anymore, I make my own dippers from a fired cartridge case with a soldered on handle. I use a case trimmer to adjust the volume until it throws what I want with my technique.
