Not a perfect picture by any means, but a quick and dirty shot of how it turned out.
Also, I totally messed up the space bar by getting the water too hot. I forgot that last time I did this, I just got the water hot, turned off the flame, let it cool a little, then dropped the caps in. You don't need boiling hot water to do it, just warm water. It works fantastically, but the smell is awful. Now I want to dye something crimson.
Also note, while I thought the different base color would make some darker than others, it doesn't. They turned out the same. And since it changes color so quickly, the only way I really see getting a lighter and darker color is by quickly dipping the caps in, then pulling them out within 30 seconds (though that might even be too long). You can dye a batch of caps in minutes with the dye. Only fabric really needs that longer time.
