Mmmm, so I decided to do that side by side of Skin Food's Ice vs Eyeko's Pastel Polish.I think the colours are reasonably close, however, there are some really obvious differences.
Firstly, the Eyeko is a 'truer' blue than Ice, which is paler and cooler in tone.
Also, while Ice is a true cream, Pastel Polish has a definite shimmer to it.
Finally, I much prefer the finish on the Pastel Polish than Ice. The Eyeko shines and gleams whilst the Skin Food looks alot 'thicker' on the nail and a little dull.
But they are close and, if you weren't looking for the differences like I am, I don't believe you could tell these two apart.
Having said that, these polishes are both available for under $5 at the moment so, if the point of a dupe is to find a cheaper option, then you're really only saving pennies here. And, if you're like me - a lacquer-holic - you'll probably end up buying both, right?
