I have two thermals from Echoes Polish to show you today! Happily Ever After is a tri-thermal shifting from a warm purple when cold to a fuchshia pink when warm to a very pale lilac-leaning blue when hot, and has heavy gold flake shimmer throughout. The April 2015 Thank You thermal (Echoes polish creates a limited edition thermal each month and sends them out free in orders of 5 or more polishes) is a blue-purple when cold changing to a bright hot pink when hot, and also has shimmer.
Happily Ever After is shown on my index and middle fingers, April 2015 on my ring, pinkie and thumb. I used three coats each plus topcoat, and both had great formulas. No sun when I wore these, so all photos are either in shade or with flash.
