How to determine and identify the background color index of cells in Excel?

Author Sun Last modified

When you receive a sheet with multiple colorful cells as below screenshot shown, in some cases, you may want to identify the background color index of these color cells. There is no built-in feature that can determine the color index of a cell, but, in this article, I introduce some VBA codes to solve this job in Excel quickly.

Do as following steps to determine the color of the cell by VBA.

1. Press Alt + F11 keys to enable the Microsoft Visual Basic for Application window.

2. Click Insert > Module to open a new Module and paste below VBA code to the blank script. See screenshot:

VBA: Get traditional hex code of cell

Function getRGB1(FCell As Range) As String
'UpdatebyExtendoffice20170714
    Dim xColor As String
    xColor = CStr(FCell.Interior.Color)
    xColor = Right("000000" & Hex(xColor), 6)
    getRGB1 = Right(xColor, 2) & Mid(xColor, 3, 2) & Left(xColor, 2)
End Function

3. Save the code and close the VBA window. Select a blank cell next to the colored cell, type this formula, =getRGB1(A16), then drag the autofill handle over the cells you want to use. See screenshot:

Tip: there are some other codes can identify the color index of cell.

1. VBA: Decimal value for each code

Function getRGB2(FCell As Range) As String
   'UpdatebyExtendoffice20170714  
    Dim xColor As Long
    Dim R As Long, G As Long, B As Long
    xColor = FCell.Interior.Color
    R = xColor Mod 256
    G = (xColor \ 256) Mod 256
    B = (xColor \ 65536) Mod 256
    getRGB2 = "R=" & R & ", G=" & G & ", B=" & B
End Function

Result:
A screenshot showing the RGB color values result

2. VBA: Decimal values

Function getRGB3(FCell As Range, Optional Opt As Integer = 0) As Long
 'UpdatebyExtendoffice20170714
    Dim xColor As Long
    Dim R As Long, G As Long, B As Long
    xColor = FCell.Interior.Color
    R = xColor Mod 256
    G = (xColor \ 256) Mod 256
    B = (xColor \ 65536) Mod 256
    Select Case Opt
        Case 1
            getRGB3 = R
        Case 2
            getRGB3 = G
        Case 3
            getRGB3 = B
        Case Else
            getRGB3 = xColor
    End Select
End Function

Result:
A screenshot showing the entire RGB color code as a long integer result
