First Mate is the perfect Navy blue. Not only is it true to the color it's supposed to be, it's a very pretty blue! It isn't too dark like some can be. It's another classic creme, like Hey Sailor, but this one is more unique. CG couldn't have gotten the shade more spot on.
Ice Cap is a really fun semi-translucent glitter. The base is clear, but kind of milky, so it does show up. That is what I used for the stripes in my mani. I think they show up really well even though the color is translucent, which means it's less translucent than it seems at first! It has a pretty serious amount of microglitter that flashes white, silver, green, and gold. The picture of my anchor nail to the left really shows how the glitter can flash quite brilliantly.
I freehanded the stripes and designs, then used my white Sally Hansen Nail Art Pen to make the red pop a bit more. This was kind of an afterthought, but I thought it turned out well.
