This four pack is inspired by Cake Ballin’ By Gina! 
Each Colour Mill 4pk set includes-
Mustard 20ml x1
Sunset 20ml x1
Rust 20ml x1
Burgundy 20ml x1
I love these so much!
The colors are rich because I start with candy melts and add extra candy color to either deepen or brighten them. I recommend that if you want bold colors. 
I used color mill coloring. 
The pumpkin color is orange melts with sunset and a touch of rust added. 
The yellow is yellow candy melts with mustard added. 
The rust color is red and orange melts with rust color added. 
The burgundy color is red melts with brown melts with burgundy color added.
