K-Pop Idol Skin Tones and Undertones
Most K-pop idols are analyzed as warm or neutral-warm in the Korean 12-season system, which is why golden, peachy foundation shades flatter them. Jennie of BLACKPINK reads warm and muted (Soft Autumn), Jimin and Jungkook of BTS read warm and bright (Light Spring and True Spring), while Jin and aespa's Karina sit cool (True Winter). Skin tone is how light or deep your skin is; undertone is the warm-or-cool cast underneath, and undertone is what decides your foundation shade and color season.
People search "Jennie skin tone" far more than you would guess, and they rarely mean how light or dark her skin is. They mean the undertone, the warm or cool cast underneath, because that is what you actually match a foundation or a color palette to.
So here is the quick version for a handful of idols, then how to read your own coloring the same way.
Skin tone vs undertone: what's the difference?
Your skin tone is depth: fair, light, medium, tan, deep. Your undertone is the hue beneath the surface, warm (golden, peachy), cool (pink, blue-red), or neutral. Foundation depth matches your skin tone. Foundation undertone matches your undertone. Get the undertone wrong and even the right depth looks off, too orange or too ashy.
Color season pulls it together. The Korean 12-season system reads your undertone, your depth, and your contrast, then names the palette that suits you. If you want the full picture, find your color season from a selfie.
Jennie (BLACKPINK): warm and muted
Jennie is analyzed as a Soft Autumn, warm-leaning with low contrast and a soft, muted quality. Her skin reads light-to-medium with a warm undertone, so golden-beige foundations in a natural, skin-like finish suit her better than anything pink-based or high-coverage matte. Dusty, grayed-down colors flatter her more than bright ones.
Jimin and Jungkook (BTS): warm and bright
Both lean clearly warm. Jimin reads as a Light Spring, delicate and warm, and Jungkook as a True Spring, warm with more clarity and brightness. Foundation-wise that means yellow-golden undertones, and on the color side they both light up in warm corals, peaches, and clear warm shades rather than cool jewel tones.
IU and V: golden warmth
IU is a True Spring, warm and bright, the kind of coloring that glows in warm reds and golden yellows. V of BTS is analyzed as a Warm Autumn, deeper and earthier but still firmly warm, which is why rich caramel, olive, and rust suit him. Both want warm-based foundation, not neutral-cool.
Jin and Karina: the cool-toned ones
Not every idol is warm. Jin of BTS is a True Winter, cool with high contrast, and aespa's Karina is read the same way. Cool undertones take pink-based foundation and look striking in true red, cool blue, and crisp black, the saturated cool colors that would overwhelm a Soft Autumn.
Why do so many idols read warm?
Part of it is genuine, warm and neutral undertones are common across East Asian coloring. Part of it is presentation. Stage and photoshoot lighting is often warm, and the K-beauty base-makeup look favors a glowy, golden, glass-skin finish that pushes even neutral skin warmer on camera. So an idol can photograph warmer than they test in neutral daylight, which is exactly why a real analysis uses a natural-light, no-filter selfie.

How to find your own undertone
Three quick checks, in rough order of reliability. Look at the jewelry that makes your skin look healthier, gold (warm) or silver (cool). Notice how your skin reacts to sun, tanning easily (warm) or burning first (cool). The vein test (green for warm, blue for cool) is the least reliable, especially on medium and deep skin, so treat it as a tiebreaker.
The catch is that undertone is the one thing your eyes are worst at judging on yourself, which is the whole reason color analysis exists. For a definite answer, check your undertone or run a free AI analysis that reads it from a photo in about 60 seconds.
Once you know your undertone and depth, you are most of the way to your color season, and to a foundation that finally looks like skin.
Frequently Asked Questions
What is Jennie from BLACKPINK's skin tone?
Jennie has a light-to-medium skin tone with a warm, muted undertone. In the Korean 12-season system she is analyzed as a Soft Autumn, which is why soft, golden, dusty colors and warm-based foundation suit her better than cool or bright shades.
What is Jimin's skin tone?
Jimin reads warm and light. He is analyzed as a Light Spring, a warm, delicate season, so yellow-golden foundation undertones and clear warm colors like coral and peach flatter him.
Are most K-pop idols warm or cool toned?
Most idols are analyzed as warm or neutral-warm, partly because warm and neutral undertones are common in East Asian coloring and partly because stage lighting and the glowy K-beauty base look push skin warmer on camera. Cool-toned idols like Jin (True Winter) are the exception, not the rule.
Does skin tone decide your color season?
Undertone does most of the work, but not alone. Your color season comes from undertone (warm or cool), depth (light to deep), and contrast (the gap between your hair, skin, and eyes) together. Two people with the same skin tone can be different seasons if their contrast differs.
