GREAT nude palette. These colors are more golden/bronze tones (as opposed to the taupe/rose tones of II and III). There are more shimmer colors than matte, but there's enough variey to get some really nice looks The more shimmery colors aren't overly so and still look beautiful and natural.
I've been very impressed by this product. I love that you mix it with your moisturizer instead of being forced to use whatever base is provided, as with other products. I find that I only need 2 drops to get a nice glow. Any more than that and it does get a bit orange. But with 2, it provides very natural looking color. Though a bit pricey, if you only use a couple drops at a time it last quite awhile. Great for summer, but also nice for Winter so you don't look pallid. I like that it gives you control.
