Step 2: Color your buttercream.

Picture of Color your buttercream.
You will need to separate your buttercream into 4 bowls. Using gel coloring dye one a light yellow, one a yam color (copper + a little brown) , one a a tannish color (ivory + a little brown), and leave one white. I didn't keep mine even because I knew I would use less yellow and white and more yam and tan.
