## org.eclipse.birt.report.model.api
Class ColorHandle

    java.lang.Object
      org.eclipse.birt.report.model.api.ElementDetailHandle
          org.eclipse.birt.report.model.api.ValueHandle
              org.eclipse.birt.report.model.api.ComplexValueHandle
                  org.eclipse.birt.report.model.api.ColorHandle

    public class ColorHandle

extends ComplexValueHandle

Handle to work with a color property. Works with element properties and structure members.

The application generally does not create color handles directly. It uses the method in other handle to get a color handle like:

A color property may be in the following format:

- A hexadecimal number in Java or HTML format: "#rrggbb", "#rgb" or "0xRRGGBB"
- A decimal number: "16711680"
- A CSS color name: "Red", "Green".
- A localized CSS color name.
- CSS absolute or relative format: {rgb(r,g,b)} or {rgb(r%,g%,b%)}
- A custom defined color.

     ColorHandle colorHandle = styleHandle.getColor( );

Use `ColorUtil.format(int, int)`and `ColorUtil.format(String, int)`to do the formatting work on a color value.

  `ColorUtil`, `ColorPropertyType`
