Spring Warm is a bright, warm tone that fits roughly 20–25% of Koreans. The skin reads bright and translucent with a yellow undertone, with little to no flush. In sunlight the skin reads as glowing; in shade it still reads as bright. The signature rule for this season is "high brightness, mid-to-high saturation warm colors" — those are what make the face come alive.
The most flattering colors are coral, peach, sunny yellow, ivory, and bright turquoise. Coral and peach in particular are the signature lip and blush families: applied to the lips and cheeks they make the whole face look "sun-kissed." On the other end, cool tones like burgundy, deep navy, and charcoal grey make the skin look dull and dim, so they should be avoided consciously.
Makeup direction is glow, glow, glow. Use a yellow-base light foundation, and rotate lips between coral orange, peach, and salmon pink. For eyes, champagne gold, light brown, and warm peach define the eye best, and a peach or salmon-coral blush placed on the apples of the cheeks adds the freshness Spring Warm is known for.
For accessories, gold beats silver — yellow gold and rose gold harmonize best with the warm undertone. For hair color, warm browns like honey brown and caramel are the go-to. Heavy bleaching into ash territory tends to make the skin look sallow.
The classic trap for Spring Warm is assuming "any bright color works." Cool brights — cool pink, ice blue — actually wash out the skin. The real rule is "bright AND warm" together; only colors meeting both conditions are truly yours.
