First of all I need to say that I have been using Urban Decay eye shadows most of my adult life, so I am used to great quality and and an amazing colour payoff. I will add my UD collection post soon.
The MUA palette is a bargain, retailing at £4 for 12 colours. I didn't expect it to be amazing, but it is actually ok. The one I got contains pastel colours, very delicate powder pinks, violet, blue, lime green and some neutrals. You can see all the colours in the swatches below (All the pictures were taken in natural daylight). All shades except the first one in the top row are slightly shimmery, not very pigmented and a bit powdery. To get the best results, I would recommend using a primer. Surprisingly the colours lasted on my eyelids for most of the day without creasing , so if you are looking for a cheap eye shadow palette you should definitely give this one a go. Have you ever tried their make up?
