Not very similar to the name brand.
Right off, I should say that I wouldn't honestly recommend that you purchase either of these palettes. However, there is a lot to talk about when comparing them. When the Revolution Beauty palette launched, I immediately noticed the similarities to the Melt palette. Both palettes have a similar color scheme, marijuana-themed packaging and color names, and the same leaf embossing on the shadows. However, there are very distinct differences. The Melt palette ($48) comes in cardboard packaging with a magnetic closure and has a mirror. It contains 8 shades, which effectively divided into two color-coordinated quads - a blue/green and an olive/green. These shades are very pigmented, especially the two matte shades in the middle, which came out darker on the eye than they appear in the pan. The level of pigment can actually make them more challenging to use, and blend on the eye, which can be frustrating. I also had difficulties with the shade 'Black Widow' which was extremely crumbly, making it challenging to use with a fingertip or any brush I tried. (I actually returned the palette as the shadow broke on me, and the second palette had the same issue.) The Revolution Beauty palette ($15) contains 18 shades, which much expands on the Melt palette. It also comes in metal packaging that snaps closed, with a very large mirror. There are more matte transition shades here, and some lovely purple tones as well. Overall, the shades in this palette are not nearly as pigmented as the Melt palette - you need to build them up. There are also some problematic shades here - two of the pressed glitters ('Goddess' and 'Bud') are gorgeous colors but contain really rough glitters - I wouldn't recommend using them, honestly. Additionally, 'Acapulco' and 'Haze' are two gorgeous gold colors but have some texture issues, almost turning into a cream at the touch and making them very difficult to pick up with a brush. Overall, both of these palettes are beautiful to look at and CAN create beautiful looks, but each requires some work to use. If you want to play with this green color scheme, the Revolution Beauty palette is more well rounded and is a better deal for the money, even though isn't a dupe for the Melt palette.
