Colors

When providing a value for style attributes that define a color, you can specify a generic color name or its RGB value.

This section describes how to specify a value for style attributes defining colors, such as textColor.

Syntax

{ generic-color | #rrggbb }

Note:

generic-color is any of the predefined colors supported by the language.
#rrggbb is a numerical color defined by a red/green/blue specification.

Usage

In most cases it is not possible to know what a potential end-user might expect regarding the font family. Therefore, your application should avoid the usage of explicit font families and use only the fontWeight/fontStyle/fontSize properties. A specific font family should be used only if the client can't determine a proper default font family for the desired platform.

The language defines a set of generic color names, interpreted by the front end according to the graphical capability of the workstation.

Table 1. Generic color names

white	#FFFFFF
black	#000000

darkBlue	#00008B

System color names can be used to get a color from the current theme of the workstation windowing system:

Table 2. System color names
System color name	Meaning
window	Window background.
windowText	Text in windows.
buttonFace	Face color for three-dimensional display elements.
buttonText	Text on push buttons.

infoBackground	Background color for tooltip controls.

In some cases, you may also specify a color with the RGB notation, starting with a # hash character.

Each value of the RGB color specification must be provided in hexadecimal, in the range [00-FF].

<StyleAttribute name="textColor" value="blue" />
<StyleAttribute name="textColor" value="#00FF45" />
