Working with Color

The VisualBots object model includes powerful color management functionality that can be used to indicate property states and group membership, to illustrate geometric relationships, and to enhance the visual appeal of your simulations.

You can assign color to Bot, Cell, Text, Pen, Screen, ViewField, and Axes objects. The easiest way to assign color to your objects is through the Color property, which can be assigned one of 40 built-in VisualBots Color Constants or your own custom color using Visual Basic's RGB function. For greater control of Bot and Cell colors, use the FillColor and ForeColor methods, which allow you to assign different colors to borders and fill regions.

The ColorTable object allows you to assign colors based on the value of an object's properties. Each Bot and Cell object has its own ColorTable object. You can assign one of the 20 built-in color table palettes to a ColorTable through the Palette property and then adjust the palette using the Lightness and Reverse properties. You use the FillColorBy method to select a color table entry based on the value of a specific property. Below is a sampling of the built-in palettes available in VisualBots.
