Purple is directly opposite yellow on the color wheel and is therefore its complementary color, so a water-soluble purple dye is applied to your teeth to neutralize any yellow undertones.
How and when should I use V34 Colour Corrector Serum?
V34 is best used as a post-whitening treatment, but it can be used daily on its own or before an event, to eliminate unwanted yellow undertones on your teeth.
