I definitely love this kit and I’ve been using it for more than a half a year. But there are some disadvantages in it. So about each color in order.
The powders are fine-grained, they are the softest. I’ve never tried anything like these before. The scent is the same of all the pans, but it’s only noticeable in the kit. All the powders are great to apply and difficult to overdo with.
Light ones:
1) Vanila
It’s a powder with a light shade of pink and orange. It is almost invisible while application. It has a "soft focus" effect. It’s very good for the under eye area. Because of the color, it is suitable for highlighting the under eye circles and saggy skin below them. It sets the concealer well.
2) Banana
Yellow powder made for highlighting or setting the whole makeup. It won’t highlight fair skin. But on a tanned girl it'll look great as a matte highlighter. As for me, I use it as the finishing powder (you can see it by the refill pan).
3) Sand
That’s a highlighter with a very small shimmer. It’s of beige color and I don’t like to contour with it, because of the glitter. I prefer highlighting with creamy textures. But it’s really subjective. I also use it as an eyeshadows, and also to contour the upper lip and the bridge of my nose.
Dark ones:
1) Java
Very intense color, in comparison with the others, it applies very brightly. The color has pink undertones but in reality it looks red on fair skin. I don’t know where to apply it. I've used it only once or twice.
2) Fawn
A good color for contouring. It’s grey, but not much. It's like a natural shadow, but not very natural as there’s a bit of red to it. But really, only a professional makeup artists can cope with absolutely grey color and not make the face look muddy and streaky. It’s difficult to apply too much of that color, it’s not applied very intensively. I definitely love it. It’s also very great for the crease.
3) Havana
That’s a bronzer, which is logical that it has orange undertones to make your face look more tanned and sun kissed. Unfortunately I’m not a fan of bronzers even in summer as they look red on me, but for those who love suntan, it’ll be great. All in all I've used it only once.
In conclusion I want to say, that it’s absolutely up to you to decide whether you’re ready or not to pay for the 6 shades whilst in reality you use only 4, but they are worth that price. I think you can buy a magnet kit and buy those refill pans which you really need.
