AnyLogic animates all flowcharts at model runtime by displaying information that can be helpful in understand the progress of the simulated processes. The basic color scheme for most of the Process Modeling Library blocks in the simulation window includes a range of colors (from silver to dark blue) to distinguish the current state of a block.

Initially, a basic two-color scheme is used for all blocks:

silver		Indicates that agents have not entered the block yet.
light blue		Indicates that agents have entered this block, but it is currently empty, that is, there are no agents inside.

By default, all blocks are silver. Block becomes light blue after an agent passes through it (that is, blocks like  Source,  Sink,  Split,  Combine, and so on).

The complex color scheme uses dark blue as the third color to visually describe the processing of actions in blocks such as  Delay,  Queue,  Service,  Conveyor,  MoveTo,  RackStore,  RackPick,  Assembler,  Batch, and so on.

Light blue and dark blue

Indicate that the block currently contains agents and an action is being processed.

The progressing of actions in the block is visualized by the moving dark blue horizontal or vertical bar (depending on the type of block).

For example, in the  Delay block this bar indicates the remaining delay time for an agent currently residing in that block, in the  Queue block it indicates the current number of agents in the queue, and in the  Conveyor and  MoveTo blocks it indicates the movement of an agent along the specified route.

The Process Modeling library contains a number of blocks with custom color schemes used to indicate their states or actions.

The  Hold block has a custom color scheme to describe its state:

Lime green		Indicates a “ready to function” state or functioning without blocking agents.
Lime green with question mark		Indicates functioning in “conditional” mode.
Red		Indicates that the Hold block is currently blocking agent(s).

 ResourcePool has a custom color scheme describing its state:

Silver		This color indicates that resources defined by this ResourcePool block have not accomplished any tasks yet.
Light blue Dark blue		This color indicates that resources defined by this block have already completed or are currently completing a task. When the vertical bar is this color, it indicates the current block load.
Linear gradient (light blue -> lime green -> gold -> orange -> red)		The color of the segment on the left side of the block indicates the total load of the block over the entire runtime.

 RestrictedAreaStart and  RestrictedAreaEnd have two colors to indicate their status:

lime green		Indicates a working state, not blocking the entry.
red		Indicates a working state, blocking the entry.
