I have two ColorStay palettes - in 'Coffee Bean' and 'Plum to Perfection'. I quite like the former and I've been using it for my low key everyday makeup look. I can also build up the shades for a more dramatic look when I want to do so. However with the plum palette I found that the pigmentation was really lacklustre and I've barely used it.
These eye shadows do last all day and they don't gather in the eyelid crease, which is the mark of a good shadow for me. However, for the rather hefty price I think there are more affordable alternatives that would do a similar job.
I first borrowed this from a friend but I loved the colour combination and brought it myself. I love the natural colours, and it stays on for hours without fade. Love it! I would absolutely recommend this to anyone. Worth the price.
