Help Needed creating ENUM for a .ctl

I have declared on the general section of the UserControl Code window:

Public ENUM bgColor
myWhite = 0
myBlack = 1
myGreen = 2
... etc.
End ENUM

and used the ActiveX control Interface wizard to associate a new Property named bgColor to a textbox.BackColor property but it won't function (Design time), I keep getting the original colors by Microsoft.
