- Method Detail
  - getDefaultColors
```
public static List<Color> getDefaultColors()
```
    Returns the list of default colors. These colors are used as default when no style is explicitly specified for a chart renderer. You can modify the contents of this list, which lets you control the global color scheme used by the application.
    
    See Also:
    
    IlvChartRenderer.getDefaultColors()
  - getDefaultColor
```
public static Color getDefaultColor(int idx)
```
    Returns the default color at the specified index.
    
    See Also:
    
    getDefaultColors()
  - generateColors
```
public static Color[] generateColors(int size)
```
    Creates an array of colors. The generated colors are taken from the default colors list and optionally completed with random colors.

  - getGradient
```
public static IlvLinearGradientPaint getGradient(int type,
                                                 Color color)
```
    Returns a gradient according to the specified color and type.
    
    Parameters:
    
    type - The gradient type: HORIZONTAL_GRADIENT, VERTICAL_GRADIENT, UP_DIAGONAL_GRADIENT or DOWN_DIAGONAL_GRADIENT.
    
    color - The considered color. The gradient is built using several colors derived from this color.
    
    Returns:
    
    The corresponding gradient. The returned gradient adapts itself to the bounds of the shape used for drawing.
    
    Throws:
    
    IllegalArgumentException - If color is null.

```
    Returns a gradient that emulates a 3-D lighting effect on a sphere. The returned paint is designed to fill a circular shape. For example, you can use this paint as the fill paint of a rendering style associated with a bubble chart renderer.
    
    Parameters:
    
    sphereColor - The original color of the sphere.
    
    lightColor - The light color.
