You thought you had found the right foundation, but in the daylight your face turns yellow while your neck remains neutral. On social networks, this very banal concern gave birth to a stunning colorimetry trick. And it starts with a purple blush.
In late January 2026, makeup artist and content creator Rose Siard, founder of Rose and Ben Beauty, posted a video that went viral. She applies a foundation that is too warm, adds around ten small touches of Rare Beauty purple blush, then blends it all in with her finger; in the comments, Internet users talk about , comments a user cited by Elle.
Foundation too yellow: where does the shift come from?
Very often, we choose our foundation only according to whether it is light or dark, without taking into account the undertone: yellow, neutral or pink. The face then appears warmer than the neck, especially in natural light.
Another factor: certain foundations oxidize over hours upon contact with air, sebum or cream, and turn even more yellow, or even orange. This is where a little purple can make up for it.
Purple blush and too yellow foundation: the viral method
The technique seen at Rose Siard is simple: apply your foundation that is too yellow all over your face, in a thin layer. Then apply a few dots of cream or liquid purple blush to the cheeks, forehead and chin.
Using your fingers, a sponge or a brush, you blend the blush into the foundation until the color rebalances. The yellow softens, the purple disappears, and you obtain a more neutral beige, better suited to your skin tone.
Color theory: why purple corrects a foundation that is too yellow
On the color wheel, yellow and purple face each other: they are complementary colors. When they mix, they neutralize each other visually, and the shade of the foundation returns to a more balanced beige.
This principle is the same as for purple correctors and anti-dull complexion bases, designed to awaken complexions that tend towards yellow. To limit failures, always test your next foundation on the jawline, in natural light, and check that the undertone remains neutral after a few minutes.
