In this image, from the video game Dishonored, we see the visual hierarchies of color, spatial layout,
and shape. As shown in this image color is the primary visual hierarchy
designed to set it apart and make it obvious. There are three colors, each used
to designate a different type of object. Yellow, the most obvious and
eye-catching color attracts the player’s eyes to enemy locations. Blue is used
to identify environmental objects such as security systems and watch towers.
Green is used to show the location of items such as weapons and food. Shape is
also an important factor in this image. Without being told what the colors
represent the player can immediately tell by the shape of the objects what is a
person, what is an item, and what is an alarm. The items are very small in
comparison to everything else, the enemies can be identified by their shape
because it is obvious that they have legs, arms, and a head. Finally, spatial
layout is important to this image. The use of color to highlight objects and
enemies allows the player to judge their location based on spatial depth, in
other words the player can tell what is closer to him than other things.

In the video game Batman: Arkham City two of the four primary
visual hierachies – color and motion – are used to attract the player’s
attention. In the game when the player activates “Detective Vision”, as seen in
the above image, the color hierarchy becomes the focus as different things are
categorized by different color. Enemies with ballistic weapons are orange while
other enemies are blue, and melee weapons are yellow. While the color hierarchy
does become the focus when in this mode, it still supplements the visual
attraction of movement. The color makes the movement of enemies more obvious
and eye catching, enabling the player to easily track the movement of their opponents
in the middle of a large fight as well as diverting focus to the nearest
enemies that move towards them to attack. Even when a player’s attention is
driven to the orange enemies by color, immediately when another enemy
approaches the movement draws the players’ attention.
