background color code of a cell and get this color RGB properties in a cell

I believe you wish to read out the RGB code for the color of a particular cell. You need user a defined function in VBA to do this. Found the code on-line, here:

https://excelribbon.tips.net/T010180_Determining_the_RGB_Value_of_a_Color.html

Adopted it a bit so that it gives the output that you desire.

Function getRGB(rcell) As String
    Dim C As Long
    Dim R As Long
    Dim G As Long
    Dim B As Long

    C = rcell.Interior.Color
    R = C Mod 256
    G = C \ 256 Mod 256
    B = C \ 65536 Mod 256
    getRGB = R & ";" & G & ";" & B
    
End Function

  Enter a formula as usual, assuming the coloured cell is A1:

=getRGB(A1)
