I picked out Rich Chocolate (Shade 4) a matte finish eyeshadow and Mink (Shade 6) which has a pearl finish. I realise I own a lot of similar colours already but at £1.50 each, I thought it would be interesting to compare these to my more expensive neutrals. Both eyeshadows are less pigmented than I am used to (the swatches are both multi-passes on bare skin) but they are buildable and all that is required is a good laydown brush and patience.
Mink is a little smoother in texture than the matte Rich Chocolate. Mink is one of those amazing, complex silvery taupes with hints of plumminess in there too. It makes a beautiful lid colour. The pearl/iridescent finish might be a little too much for everyday but the colour holds up very well to more expensive taupes that I possess.
Rich Chocolate is lighter in the swatch than I was expecting. It looks quite warm compared to mink and a medium rather than 'rich' chocolate brown but when used as a crease colour layered over Mink, it definitely looks darker. The two colours also sit better together than you might imagine from the swatches.
I applied these over a primer and was very impressed with the eye look I achieved. It took more effort than my high end favourites but I didn't have any blending issues which is a pet peeve with cheaper eyeshadows. These are made by the same people than make MUA cosmetics, so I suspect if you have similar colours from one, you may not need to duplicate. If you're ever in Tesco, these are well worth a browse.
