Colors for Bath Bombs

For making bath bombs, it is recommended to use water-soluble colors, especially those with an "EasyWash" feature. These colors dissolve well in water and are less likely to leave stains on the bathtub or skin.

Based on the search, suitable colors include:

• Brilliant Blue‎ (CI42090) EasyWash™
• Black Color EasyWash™
• Acid Violet 17 EasyWash™
• D&C Blue No.2 (Indigo Carmine) EasyWash™
• Caramel Color EasyWash™

These colors are highly concentrated, so you only need to use a very small amount to achieve the desired shade. Always add a little at a time and mix until you get the color you want.
