The irradessent gold is also a blending color. Squirt it OVER other bolder colors to saturate and blend them into each other. WAY cool! I have many glimmer mists but the gold is so subtle and blendy - I use it way more than any others.
I depends on what you like. I layer them a lot, but I def use dazzling Diamonds, Sapphire, Suede, Candy Apple Red, Patina, Vintage Pink, English Ivy and Antique Brass a lot. I have a lot of colors, but I think I use those the most.
I only have three right now, but I'm loving Raven. I love it's versatility. Sometimes it comes out a grey/blue color and sometimes it's a darker purplish color. It's very pretty. I've used it on some paper flowers I made.
