1. What does it mean?
웜톤 comes from warm tone. In beauty conversations it describes an appearance or palette associated with warmer color families, and it is also used to group makeup shades marketed as suitable for that palette.
Also written or said as womton
2. The nuance
It is not a synonym for dark skin, and it does not refer to body temperature. People use the category as a styling aid, not a requirement to avoid every cooler color.
3. Examples
“웜톤 추천 색이라도 직접 발라 보고 골랐어.”
Even though the shade was recommended for warm tones, I tried it on before choosing.
“이 팔레트는 웜톤 계열 색이 많네.”
This palette has a lot of warm-toned colors.
