# TCustomColorBox.NoneColorColor

TColor used for the clNone color constant.

## Declaration

Source position: colorbox.pas line 90

`public property TCustomColorBox.NoneColorColor : TColor read FNoneColorColor write SetNoneColorColor default clBlack;`

## Description

NoneColorColor is a TColor property with the color value used for the clNone color constant.

Like clDefault, clNone does not have any meaning without a context where it is applied. Its actual value is different for Forms, Buttons, Windows, etc. This property allows clNone to be resolved to an actual TColor value when needed.

The default value for the property is clBlack.

Changing the value for the property causes the control to be redrawn.

NoneColorColor is used in the DrawItem method to resolve the clNone color constant when drawing items in the control.

Use DefaultColorColor for the TColor value used for the clDefault color constant.

Use Style to include or exclude the clDefault and clNone color constants in the Colors for the control.
