Cells background color according to 3 cells data NOT CONDITIONAL FORMATTING

[KDS14589]

I have 4 cells. B2 is R, C2 is G, D2 is B, those represent the color palate. Under those cells are cells B3,C3,D3 that I've data restricted to numbers between 0-255. I want cell E3 to have the color reflected by the numbers I've entered in the first three cells. If I change the numbers in those cells I want the color of cell E3 to change to. I've included an image of what I'm attempting. I know it involves VBA but I don't know were to start or even where to start looking.

Private Sub Worksheet_Change(ByVal Target As Range)
    On Error Resume Next
    Dim R As Integer, G As Integer, B As Integer
    R = [B3]
    B = [C3]
    G = [D3]
    If Not Intersect(Target, Range("B3:D3")) Is Nothing Then Range("E3").Interior.Color = RGB(R, G, B)
    On Error GoTo 0
