I do hate this phrase, but I think the orange colour really does make the blue of my eyes pop!
The eye gloss lasts ok, but not all day. It is easy to touch up though and can be boosted with a primer before applying the gloss. I have mostly used the orange from the duo as find the paler, champagne shade has a bit too much glitter for day time.
I love orange on blue eyes. One of my favourite combinations! Mac valet ( LE that I got in a palette once) is so gorgeous with some black eyeliner
