The ruby is very vibrant and dark. I would not consider it warm. The gold? Yeah… I can see the gold being warm, but again, very vibrant. The pink is kinda like the inside of a shell. Its very soft, but still shiny. Its a lovely contrast, and I think thats something missing in the regular production colors (As they relate to eachother.) It just compliments the other colors so well, but is still something different. Does that make sense?
