Why can I not create a Dino with unique colors?

I’ve followed the tutorials. Read the posts, that I can find, and still I cannot get the colors to change. I’ve copied the Dino Color Set BP, made my desired edits and linked it to the Random Color Sets on the Dino Character BP with no effect. I’ve tried to link the edited Dino Color BP to the Colorization MIC but it wont take it. Where have I taken a wrong turn? How do you get the MIC files to recognize the new colors? Still want some randomness hence the editing of the Dino Color Set BP. Is it still possible to create a unique (color) dino?

Thanks in advance.
