Colors

When providing a value for style attributes that define 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 }
  1. generic-color is any of the predefined colors supported by the language.
  2. #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, avoid using explicit font families in your application and use only the fontWeight/fontStyle/fontSize properties. A specific font family is used only if the client cannot determine a proper default font family for the desired platform.

The language defines a set of generic color names, interpreted by the front-end depending on the graphical capability of the workstation.

RGB notation

When a predefined color is not what you require, you can specify the exact color with the RGB notation, starting with a # hash character:
  <Style name="Edit.mandatory">
     <StyleAttribute name="textColor" value="#50AEFF" />
  </Style>

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

Generic color names

Use generic color names, to keep your style definitions portable across several front-end types.

Note: The exact rendered color depends on front-end type.
