I'm an autumn warm tone, and I think this can be used naturally as a base lip color. When applied once, it matches my natural lip color, so if you apply it multiple times, it looks pretty on its own. My lips tend to get a lot of flakes, so the flakes were highlighted when I applied it, but the color was really beautiful. I think you'll be very satisfied if you exfoliate first and then apply it. This is the lip product I like the most out of all I've bought so far ^_^ The texture is as the name suggests—soft and powdery. Also, compared to other tint balms like Pyuna, this has a more muted color, so I think it's perfect for muted tones. For winter cool tones, the Cold Balm would be really pretty ㅜ I got interested in AOU after seeing actress Kim Ji-won's lips, and I think I made a great purchase!
