Red Dot - Where the inkling stands.

Dashed Lines - Lines in the Shooting Range.

Red Line - When the crosshair appears, or before falloff damage occurs. Effective Range.

Blue Line - The maximum range of damage. Ineffective Range.

Pink - Ink. The maximum range of this is Inking Range.

The weapons are sorted in two different ways. The top row of weapons is roughly sorted by the pink Inking Range in ascending order. The lower row is sorted by the blue Ineffective Range lines (and the red Effective Range lines when there are no blue lines) in ascending order.
