Icon Process

When discussing icons at different resolutions, there appears to be some debate. Should icons be the same, but scaled appropriately? Or, as shown here, should they vary based on resolution and what looks best at each resolution?

I think the best solution should be used for the resolution being viewed. It is unlikely that a user will see a @1x and @2x icon side by side where they can be compared. However, it is more likely (in my opinion), that a user will see that details are unevenly added, detail seems too high/low, or the “pixels seem blurry” because the solution is not a pixel perfect icon.

One can see more examples of YouMap from some of our other dribbble posts.
