The default Java Swing Color Chooser is great. However it has some disadvantages:

• "No color" is not supported.
• You can't define a custom palette. For many situations the standard palette has too many colors, especially too many with similar values.

The CleverColorChooser has both, and both optional. Here is how to use the class:

CleverColorChooser colorChooser = new CleverColorChooser(
    "Color Chooser", // title passed to the Java Color Chooser dialog
    Color.white,     // "start color", null allowed
    colors,          // color array for custom palette, null allowed
    true             // true if "no color" is allowed
);

This is how the Clever Color Chooser looks.

1) A custom color palette and the "no color" button.

2) Only the palette button.

3) Only the "no color" button.

4) Only the color label and the button for opening the standard Java Swing Color Chooser.
