Remarks

You can set this property to any valid ARGB (alpha, red, green, blue) value. Note that for the Chart object, the alpha component cannot be set to a value other than 255. This also means that, for the Chart object only, a Transparent value cannot be used.

The BackColor value will be the first color used if you are using gradient colors for the background.

The alpha value controls the opacity of a color. If you set this color to "transparent" - that is, if you use an alpha value of 0 - no color will be assigned to the background of the title. As a result, the background will be transparent.
