Color Selections |

The Color Selections window presents different formats for specifying a color or creating a custom color. The color format may be a predefined system color, an RGB setting, HTML Hex color codes, a user defined color or a string expression.

To invoke this window, select the color Query button associated with a color property (i.e. Background Color, Border Color, etc.). In most cases, this Query button is displayed with a paint palette bitmap, as shown in the first example below; however, in certain instances, such as Themes Maintenance and Visual Class Maintenance, it is a three-dotted button, as shown in the second example.

When the color Query button is selected, the Color Selections window is displayed:

This window consists of the following:

Current Color | Name and description of the current color.
Preview | Displays a preview of the specified color.
Standard (0-15) | Pre-defined system color (i.e. Dark Gray, Black, Dark Red, Light Red, Dark Green, Light Green, Dark Yellow, Light Yellow, Dark Blue, Light Blue, Dark Magenta, Light Magenta, Dark Cyan, Light Cyan, Light Gray, White).
