According to Guerlain…
Harmony 01 / Teint Rose corrects by using mauve to reflect light and brightening the complexion along with green to reduce redness; pink to give skin a more even look; and white for illumination, gold for “radiance.”
This particular Meteorite has a blend of champage, white, yellow, green, pink, and purple pearls that create a soft, subtle micro-shimmered glow. It’s a very silky and finely-milled product–this is not powdery, heavy, or cakey. It doesn’t feel heavy, and it never looks unnatural.
Admittedly, it is difficult to see the nuances between the three Meteorites. Even in person, they don’t look terribly different on me when applied. Teint Rose is less golden, more white/champagne shimmer, while Teint Dore is a little more golden-bronze, and Teint Beige is is still a bit bronze but less yellow. After seeing all three in person, I think any one of them would be appropriate across skin tones and undertones. They effect they have is so subtle, I can’t imagine any looking bad because of skin tone.
