Trying to work on a hue's chart in VB.net

Im trying to get the hue's to display in a selectable chart in Vb.net, but not having much luck at the moment, anyone able to point me into the right direction? (i have not done that much work with array's before - which is what im assuming you would use)

I know this isnt VB but for my GDK program I had to draw hue chart stuff and made this method.

        public static Color Convert555ToARGB(short hue)
        {
            int red = (((short)(hue >> 10)) & 0x1f) * 8;
            int green = (((short)(hue >> 5)) & 0x1f) * 8;
            int blue = (hue & 0x1f) * 8;
            return Color.FromArgb(red, green, blue);
        }

And what you can do is take Hue.Colors and for each of the short values in Hue.Colors you pass it through this and it will return a 32 bit color to use as you please.

Public Shared Function GetColorFromHue(ByVal hue As Short) As Color
    Return Color.FromArgb(((hue And &H7C00) >> 7), ((hue And &H3E0) >> 2), ((hue And &H1F) << 3))
End Function
