I had a beauty voucher that expired in mid-May, so I bought this little square of teal, knowing that I would have use for it. In the metallic formula, ME Blue 640 (S$35) is apparently the replacement of ME Blue 638, which was part of the older, discontinued ME range*.
Unlike the metallic shadows of old, it isn’t exceptionally pigmented – the swatch took several swipes to show up as above. Nevertheless, this shadow isn’t muted in tone; instead, it has a pretty reflective effect that brightens it.
If you shy away from loud colours but would like to wear such a shade of blue, this is something to try. However, if you would like the colour to pop, use it over a cream shadow such as Shiseido Hydro Powder Eye Shadow in Proenza Schouler Blue.
