Nebula Grunge on a box

Here I used Color Mist's Lemon Yellow, Slimescent Green and Tahoe Turquoise. Sprayed the box with these colors and while wet, I oversprayed the box with Cobalt sky and then dryed with the heat gun.

I added some Copper Kettle to the lid and dried again. The box had one coat of white acrylic on it to start.
