The Bug:

Some potions are too similar in color therefore making them barely distinguishable.

Some examples include mundane and water breathing, slowness and invisibility, luck and poison, etc... Having an enlarged image of the potions side-by-side makes them more distinguishable, however, from a distance, it's incredibly hard to identify them from one another.

Steps to Reproduce:

1. Switch to creative mode and obtain both a water bottle and a water breathing potion.
2. Observe the color of them both and how they're incredibly similar.
3. Take note as to whether or not some potions are too similar in color therefore making them barely distinguishable.

Observed Behavior:

Some potions are too similar in color therefore making them barely distinguishable.

Expected Behavior:

Potions be unique in color and therefore making them distinguishable.
