These 20 new custom blend shades are created using existing EMMA ZIP DIP colors. Mix Ratio: 2-Color Blends: 1 tbsp. of each color to create 2 full tbsp. of new color. 3-Color Blends: ½ tbsp. of each color to make 1.5 tbsp. of new color. This amount should be enough to create one full set (10 short nails). Colors can experience slight discrepancies based on exact mix ratio.
