File:Grid Potion of Night Vision.png

Summary
These are somewhat of a placeholder using the particles given off when their corresponding potion effect is in… effect to get their colors. These are not perfect (at least one pixel is off, due to a color not existing), but they are close enough and will do until a.) they are found via inventory editor or b.) they are added. (Added in 12w32a, although maybe unintentionally)
