A good alternative to the vibrant and gritty colours in the Urban Decay range I would say, quite richly pigmented but more powdery. What you see in the palette is pretty true to what you will swatch if you pick up enough of the eye shadow. If you're lucky enough to have a Superdrug near you that stocks this range then it's worth an amble down there to try it. For around £5 each, it's pretty good value for 12 shades to play with.
Left: Chaos palette, 12 gorgeous and vibrant matte shades.
Right: The Original palette, again 12 sexy and metallic colours.
