If I use the standard ColorDialog control to select a colour (say a pale blue) I get the returned value of 16762980 which is fine (Red=100, Green=200, Blue=255), BUT why when I use the following do I just get a transparent background???

Panel2.BackColor = Color.FromArgb(16762980)

Many thanks.

System.Windows.Forms.ColorDialog.Color is a System.Drawing.Color object. Why
do you get an integer value?

Because you set the alpha value to 0.

Using a Color structure I'd write

Color.FromArgb(255, ColorDialog1.Color)

Or:
Panel2.BackColor = Color.FromArgb(16762980 Or &Hff000000)
