TIP: For this ombre effect, you’ll want a range of color from light to dark. With these colorants, work with a “what you see is what you get” (WYSIWYG) eye. Your color outcomes may vary, but here’s a guideline:
Layer 1: A lightish blue colored with diluted Royal Blue LabColor. We used about 10 mL of colorant.
Layer 2: A slightly darker blue colored with slightly more diluted Royal Blue LabColor. For this layer, we used about 15 mL of colorant.
Layer 3: A dark blue blend of both the diluted Royal Blue LabColor and
diluted Blue Mix LabColor, heavier on the Royal Blue. For this layer, we used 9 mL of Royal Blue LabColor and and 6 mL of Blue Mix LabColor.
Layer 4: A dark greenish blue blend of both the diluted Royal Blue LabColor and
diluted Blue Mix LabColor, heavier on the Blue Mix. We used 9mL Blue Mix LabColor and 4 mL Royal Blue LabColor.
Layer 5: A greenish blue colored with just diluted Blue Mix LabColor. We used about 9 mL Blue Mix LabColor.
SIX: Add fragrance oil to each of the split batches. Keep using the whisk to mix.
SEVEN: Pour 1/2 of the Layer 1 batch into your mold.
Pour down the center of the mold from one side to another to equally distribute soap along the bottom of the mold.
Tap mold on table to eliminate any air bubbles.
